Re: WHEA-Logger Event 19 / Processor Core / Corrected Machine Check / Internal Parity Error / W541

Same Issue for me:

L540 with i7 4710MQ + Windows 10.
The Update KB4056892 was installed on 17.1.2018.

UEFI Version: 1.90 of 28.12.2017 installed on 1.2.2018

Only since 1.2.2018 Eventlog is flooded with those warnings. Today first BSOD: IRQ not less or Equal.
One day before on 31.1.2018, There is an eventlog in "Installation log" Changes for KB4048955 (November 2017 Update) beeing initiated. The current status is "replaced". Target state is "removed". Client-ID: CbsTask.

Strange enough that if I download UEFI 1.89 from lenovo Website, the Flashing Tool reports that is has the same UEFI Version as already installed. But UEFI Setup displays 1.90 and the Downgrade to be installed is 1.89.

 

In Flashlog I see more details:

[2018/2/1 13:46:41]
OS = Windows 10 64bit
Driver Loading....Done
System BIOS Version -> J4ET89WW
Applying BIOS Version -> J4ET90WW
AC adapter/Battery check....OK.

BIOS Flashing....BIOS Flash completed.


[2018/2/5 11:28:26]
OS = Windows 10 64bit
Driver Loading....Done
System BIOS Version -> J4ET90WW
Applying BIOS Version -> J4ET90WW

Re: WHEA-Logger Event 19 / Processor Core / Corrected Machine Check / Internal Parity Error / W541

Managed to downgrade UEFI BIOS to 1.88 with command line tools. No more warnings in eventlog, so fare no more BSOD.

 

The Windows Flash Tools and bootable iso file provided by Lenovo do not work as they pretend, the BIOS file was not for this hardware type.

 

C:\DRIVERS\flash\j4uj70ww>dir /B

32bit

64bit

BCP.EVS

BIOS_LOGO.TXT

chklogo.exe

j4et88ww

tpnflhlp.sys

WinFlash32.exe

WinFlash32s.exe

WinFlash64.exe

WinFlash64s.exe

wininfo.exe

winuptp.exe

Winuptp.log

 

C:\DRIVERS\flash\j4uj70ww>dir /B j4et88ww

$0AJ4000.FL1

 

C:\DRIVERS\flash\j4uj70ww>winflash64.exe /sd /sn /file .\j4et88ww\$0AJ4000.FL1

 

meaning of parameters:

SD=skip bios build date time check

SN=skip part number checking

Re: WHEA-Logger Event 19 / Processor Core / Corrected Machine Check / Internal Parity Error / W541

I just installed the newest Windows 10 Cumulative (February 13, 2018—KB4074588 (OS Build 16299.248), after previously removing the KB4056892 and back came the WHEA-Logger events again. Smiley Frustrated

 

But this time, I left the new patches in since it includes many other security patches and then I used GRC InSpectre (https://www.grc.com/inspectre.htm)  to turn off the Meltdown/Spectre patches, rebooted, and the WHEA-Logger events stopped.  Have to let the PC run for a while to see if BSOD returns. 

 

Still awaiting updates from Lenovo/Intel...

Don't leave yourself open to Meltdown unnecessarily: I'd suggest trying only having Spectre mitigation disabled with InSpectre. (Based on info in T440s thread here, and it has proven sufficient on my T440s.)

Yes, using inSpectre.exe to turn on Meltdown protection, leaving Spectre off does not generate any more of the WHEA-Logger errors. 

 

Have to wait a week or so to verify no blue screens.

(After I turned off both protections a couple weeks ago, I no longer had blue screens.)
