Based on your response / observation it looks like there is something fishy regarding Intel Xe GPU driver + update for Gen2 docks firmware in 1.08 BIOS.

I also tried latest drivers for Intel Xe GPU (ver. 27.20.100.9466) but no change - still got WHEA BSOD while device_enabled+drivers_installed for Realtek Card Reader.

thanks, seems to work by only disabling realtek PCIE card reader in device manager. Before I was uninstalling the driver and removing it in BIOS and it still crashes. So basically just disable and leave it at that, don’t uninstall anything or do any extra steps.

Let's hope that they'll fix it soon.

Same problem here with L13 Yoga G2.

 

Even Lenovo telephone support was unable to tell me how to downgrade the bios. That's horrible! This should be possible.

I tried several BIOS Update Boot CDs without success and various error messages.

 

I still get the Error with KB5001330 uninstalled and Card Reader disabled. I tried various Graphics Driver Versions - no success.

 

Lenovo, maybe you could provide a new fixed bios, please. Also the old version named as new version to allow flashing would be a great thing!

 

Thanks!

 

EDIT: It seems, that Deinstalling the Card Reader driver helped...

Re:L13 Gen2 bios 1.08 - Win10 BSOD - RealTek vs Intel driver

From my experience so far:

- fresh Windows 10 20h2 with March 2021 update with most drivers installed except driver for Realtek Card reader - got WHEA BSOD

- fresh Windows 10 20h2 with April 2021 update with most drivers installed except driver for  Realtek Card reader - got WHEA BSOD

- tried to disable device Realtek Media Card Reader in Windows, and also in BIOS - no success, still WHEA BSOD (which previously seems to work, but it was just an illusion)

 

With BIOS 1.06 and Win10 20H2 + April 2021 update OS is usually working and usable (but crashes with BSOD sporadically - you can find couple of similar WHEA BSOD not only on ThinkPads with your favorite search engine, and couple of mentions on ThinkPads arised circa in November 2020).

 

Today I had to uninstall Intel Xe Iris GPU, because once drivers kicked in system got BSOD WHEA - again !!

Maybe another attempt to fix this WHEA BSOD (bold font are required steps, but all steps are recommended):

- uninstall Intel Iris Xe GPU drivers via devmgmt.msc (also check "Delete drivers for this device")

- reboot

- open regedit -> HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers

- create new QWord (64bit OS) / DWORD (32bit OS) named "TdrDelay" and set it to Decimal 10 (default is 2 if not set by registry editing)

    2 seconds correspond with my observation bacuse first my desktop "freezes" with movable mouse, but nothing can be clicked - no reactions from OS/apps.

    Then cca after 2 seconds even mouse cursor freezes on desktop and almost "instantly" I had BSOD WHEA.

- reboot (still VGA drivers here, no video acceleration)

- install Intel Iris Xe GPU drivers from Lenovo

- reboot

- system is working at least for 15-20 minuts without BSOD for now

 

What's strange that previous BIOS 1.06 everything seems fine - but maybe BIOS 1.08 bugfix revealed another bug/s somewhere else.

Also I do not understand why changing some BIOS settings in 1.08 are not "applied" - only label is changed from enable to disable and vice versa.

0 person found this solution to be helpful.

This helped me too
