cmos checksum error hiper-v

Next to that I had a bad cmos checksum which I also got after reinstering the MOBO battery might that be related? Solution: I can't find a definite answer if the processor will operate when only two of the four memory slots are populated.

We are seeing more issue with fsnotify related callbacks. These are not a soft/hard lockup but seem to significantly degrade the responsiveness of systemd (and from there everything else).

The following upstream commit may fix this issue, but it is in Paul's RCU tree and not in linux-next or upstream yet:

https://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git/commit/?h=dev&id=1a05c0cd2fee234a10362cc8f66057557cbb291f

srcu: Lock srcu_data structure in srcu_gp_start()
The srcu_gp_start() function is called with the srcu_struct structure's
->lock held, but not with the srcu_data structure's ->lock. This is
problematic because this function accesses and updates the srcu_data
structure's ->srcu_cblist, which is protected by that lock. Failing to
hold this lock can result in corruption of the SRCU callback lists,
which in turn can result in arbitrarily bad cmos checksum error hiper-v commit therefore makes srcu_gp_start() acquire the srcu_data
structure's ->lock across the calls to rcu_segcblist_advance() and
rcu_segcblist_accelerate(), thus preventing this corruption.

Please investigate this issue and evaluate the proposed fix.



Note - This chapter applies to all Sun Fire X4100/X4100 M2 and X4200/X4200 Cmos checksum error hiper-v servers, unless otherwise noted.



This appendix contains information about how the servers process and log errors. See the following sections:

Handling of Uncorrectable Errors

This cmos checksum error hiper-v lists facts and considerations about how the server handles uncorrectable errors.



Note - The BIOS ChipKill feature must be disabled if you are testing for failures of multiple bits within a DRAM (ChipKill corrects for the failure of a four-bit wide DRAM).



  • The BIOS logs the error to the SP system event log (SEL), through the board management controller (BMC).
  • The SP's SEL is updated with the failing DIMM pair's particular bank address.
  • The system reboots.
  • The BIOS logs the error in DMI.


Note - If the error is on low 1MB, the BIOS freezes after rebooting. Therefore, no DMI log is recorded.



  • An example of the error is reported by the SEL through IPMI 2.0 is as follows:
    • When low memory is erroneous, the BIOS is frozen on pre-boot low memory test because the BIOS cannot decompress itself into faulty DRAM and execute the following items:

    • When the faulty DIMM is beyond the BIOS's low 1MB extraction space, proper boot happens:

  • Note the following considerations for this revision:
    • Uncorrectable ECC Memory Error is not reported.
    • Multi-bit ECC errors are reported as.
    • On first reboot, BIOS logs a HyperTransport Error in cmos checksum error hiper-v DMI log.
    • The BIOS disables the DIMM.
    • The BIOS sends the SEL records to the BMC.
    • The BIOS reboots again.
    • The BIOS skips the faulty DIMM on the next POST memory test.
    • The BIOS reports available memory, excluding the faulty DIMM pair.

FIGURE E-1 shows an example of a DMI log screen from BIOS Setup Page.


Graphic showing a sample DMI log screen.


Handling of Correctable Errors

This section lists facts and considerations about how the server handles correctable errors.

  • During BIOS POST:
    • The BIOS polls the MCK registers.
    • The BIOS logs to DMI.
    • The BIOS logs to the SP SEL through the BMC.
  • The feature is turned off at OS boot time by default.
  • The following Linux versions report correctable ecc syndrome and memory fill errors inif kernel flag is indicated at boot time, or if is enabled through kernel compile or installation:
    • RH3 Update5 single core
    • RH4 Update1+
    • SLES9 SP1+
  • The Linux kernel () repeats a report every 30 seconds until another error is encountered and a flag is reset.
  • Solaris support provides full self-healing and automated diagnosis for the CPU and Memory subsystems.
  • FIGURE E-2 shows an example of a DMI log screen from BIOS Setup Page:

Graphic showing a sample DMI log screen, with a correctable error shown.


  • If during any stage of memory testing the BIOS finds itself incapable of reading/writing to the DIMM, it takes the following actions:
    • The BIOS disables the DIMM as indicated by the Memory Decreased message in the example in FIGURE E-3.
    • The BIOS logs an SEL record.
    • The BIOS logs an event in DMI.

Graphic showing a sample DMI log screen, with a correctable error and memory decreased message.


Handling of Parity Errors (PERR)

This section lists facts and considerations about how the server handles parity errors (PERR).

  • The handling of parity errors works through NMIs.
  • During BIOS POST the NMI is logged in the DMI and the SP SEL. See the following example command and output:

  • FIGURE E-4 shows an example of a DMI log screen from BIOS Setup Page, with a parity error.

Graphic showing a sample DMI log screen, with a PCI parity error shown.


  • The BIOS displays the following messages and freezes (during POST or DOS):
  • The Linux NMI trap catches the interrupt and reports the following NMI "confusion report" sequence:



Note - The Linux system reboots, but does not inform the BIOS of this incident.



Handling of System Errors (SERR)

This section lists facts and considerations about how the server handles system errors (SERR).

  • System error handling works through the HyperTransport Synch Flood Error mechanism in the AMD controller.
  • The following events happen during BIOS POST:
    • POST reports of any previous system errors at the bottom of screen. See FIGURE E-5 for an example, cmos checksum error hiper-v.

Graphic showing a sample POST screen, with system error listed.


    • SERR and HyperTransport Synch Flood Error are logged in DMI and the SP SEL. See the following sample output:

  • FIGURE E-6 shows an example DMI log screen from the BIOS Setup Page with a system error.

Graphic showing a sample DMI log screen, with a system error listed.


Handling Mismatching Processors

This section lists facts and considerations about how the server handles mismatching processors.

  • The BIOS performs a complete POST.
  • The BIOS displays a report of any mismatching CPUs, as shown in the following example.


Note - The following example report, the names of the Cmos checksum error hiper-v controllers in the original Sun Fire X4100/X4200 are used.



  • No SEL or DMI event is recorded.
  • The system enters Halt mode and the following message is displayed.

Hardware Error Handling Summary

This section contains a table that summarizes the most-common hardware errors that you might encounter with these servers.

 


Error

Description

Handling

Logged (DMI Log or SP SEL)

Fatal?

SP failure

The SP fails to boot upon application of system power.

The SP controls the system reset so the system may power on but will not come out of reset.

  • During power up, the SP's boot loader turns on the power LED.
  • During SP boot, Cmos checksum error hiper-v startup, cmos checksum error hiper-v, and SP sanity check The power LED blinks.
  • The LED is turned off when SP management code cmos checksum error hiper-v IPMI stack) is started.
  • At exit of BIOS POST the LED goes to STEADY ON state.

Not logged

Fatal

SP failure

SP boots but fails POST.

The SP controls the system RESET so the system will not come out of reset.

Not logged

Fatal

BIOS POST failure

Server BIOS does not pass POST.

There are fatal and non-fatal errors in POST. The BIOS does detect some errors that are announced during POST as POST codes on the bottom right corner of the display on the serial console and on the video display. Some POST codes are cmos checksum error hiper-v to the SP for logging.

The POST codes described above do not come out in sequential order and some are repeated, because some POST codes are issued by code in add-in card BIOS expansion ROMs.

In the case of early POST failures (for example, the BSP fails to operate correctly) BIOS just halts without logging.

For some other POST failures subsequent to memory and SP initialization, the BIOS logs a message to the SP's SEL.

 

 

Single-bit DRAM ECC cmos checksum error hiper-v

With ECC enabled in the BIOS Setup, the CPU detects and corrects a single-bit error on the DIMM interface.

The CPU corrects the error cmos checksum error hiper-v hardware. No interrupt or machine check is generated by the hardware. The polling is triggered every half-second by SMI timer interrupts, and is done by the BIOS SMI handler.

The BIOS SMI handler starts logging each detected error, and stops logging when the limit for the same error is reached. The BIOS's polling is disablable through a software interface.

SP SEL

Normal operation

Single four-bit DRAM error

With CKIP-KILL enabled in the BIOS Setup, the CPU detects and corrects for the failure of a four-bit-wide DRAM on the DIMM interface, cmos checksum error hiper-v.

The CPU corrects the error in hardware. No interrupt or machine check is generated by the hardware, cmos checksum error hiper-v. The polling is triggered every half-second by SMI timer interrupts, and is done by the BIOS SMI handler.

The BIOS SMI handler starts logging each detected error, and stops logging when the limit for the same error is reached. The BIOS's polling is disablable via a software interface.

SP SEL

Normal operation

Uncorrectable DRAM ECC error

The CPU detects an uncorrectable multiple-bit DIMM error.

The "sync flood" method of handling this is used to prevent the erroneous data from being propogated across the HyperTransport links. The system reboots, the BIOS recovers the machine check register information, maps this information to the failing DIMM (when CHIPKILL is disabled) or DIMM pair (when CHIPKILL is enabled), and logs that information to the SP.

The BIOS will halt the CPU, cmos checksum error hiper-v.

SP SEL

Fatal

Unsupported DIMM configuration

Unsupported DIMMs are used, or supported DIMMs are loaded improperly.

The BIOS displays an error message, logs an error, and halts the system.

CMOS contents failed the Checksum check.

The BIOS displays an error message, logs the error to DMI, and boots.

DMI Log

Non-fatal

Unsupported CPU configuration

The BIOS supports mismatched frequency and steppings in CPU configuration, but some CPUs might not be supported.

Well it seems to have escalted, but it does tell me more about the problem. Now I get the "Your PC needs to be repaired" message with multiple drivers missing and header checksum doesnt match computed checksum for winload.exe. I still have my usb with a fresh Windows 10 install, but when I set my usb as the main boot device I keep getting the error 0x00000c21 and it reboots. Is the usb faulty too? Also there seems to be a power problem too as my PC couldn't power up multiple times. My PSU was making a buzzing noise which had something to do with the carburetor I believe.

Even with the slow boot times once I got into Windows I couldn't see any indication that my drive was dieing. Nothing got slower, cmos checksum error hiper-v, on the contrary it actually got faster after the fresh insta.

So yeah everything seems to be going cmos checksum error hiper-v. I don't have access to a PC right now so it's pretty difficult to solve this. I do however have some old c drives but first I must secure my data.



Hi - I agree with konawolv - sounds like your HD is failing or has already failed.

But depending on the age of your "Hardware" it might also be related to a defective PSU, MOBO, or overheating issue caused by thick layer of dusts on your vital components. When you reinstalled windows did you reinstall "over the older version" of did you backup your data files, nuke the drive, and then performed a "Clean Install" followed by all the the updates etc, etc?

Assuming that we are not talking about a laptop or notebook(if this is wrong than the below will have to be slightly modified) I have a few question and a suggestion or two for you -

QUESTIONS
1) How old is your PC? Where not talking about a laptop or notebook . correct?
2) Which version of Windows are you running?
3) Is your PC powered on for long periods of time?
4) Have you ever examined or cleaned the PSC, MOBO, Heat Sink, RAM, Intake/Exhaust fans of built up layers of dust?

SUGGESTIONS
1) You might want to open the side panel of the case/tower and see how bad the dust has built up. Remove as much dust as you can.
2) If you have important data on that HD - don't continued to attempt to power it up. If you have a friend with Laptop you could:
- Purchase a USB-IDE/SATA interface cable with power brick for about $29.00USD;
- Remove the HD from the tower;
- Set the HD's jumper plug to "Slave Mode";
- Connect the the cable and power cmos checksum error hiper-v to your HD;
- Connect the USB end to your friend's laptop USB slot;
- Power on the brick;
- On the laptop - click on "Computer" and verify that the laptop see your HD;
- Select the Icon for your HD and then locate the data file you want to copy;
- Using an appropriate size Flash drive - copy your file.

If you have any question let us know.

Good Luck!

Tom
