Issue #392 has been updated by Pawel Radomychelski.

- Image of BSOD attached. No additional information.
Strange that there is no more specific error code.
- How can i create coreboot.log of both images?
If your Linux kernel is recent enough (maybe from backports), and has `GOOGLE_MEMCONSOLE_COREBOOT` selected
$ grep MEMCONSOLE /boot/config-5.18.0-2-amd64 CONFIG_GOOGLE_MEMCONSOLE=m # CONFIG_GOOGLE_MEMCONSOLE_X86_LEGACY is not set CONFIG_GOOGLE_MEMCONSOLE_COREBOOT=mthen
sudo modprobe memconsole-coreboot sudo less /sys/firmware/logOtherwise: In the coreboot source tree, `make -C util/cbmem` and `sudo util/cbmem/cbmem -1`.
Attached both /sys/firmware/log from CoreBoot 4.15 and 4.17. Thanks

* Author: Pawel Radomychelski * Status: New * Priority: Normal * Category: board support * Target version: 4.17 * Start date: 2022-06-18 * Affected versions: 4.16, 4.17, master * Related links: https://ticket.coreboot.org/issues/327 * Affected hardware: Lenovo ThinkPad X230 Tablet * Affected OS: Windows 10 ---------------------------------------- Since CoreBoot 4.16 my Windows 10 cant boot from SeaBios, i get BSOD with "ACPI Error" very early.
Don't know which commit exactly brakes ACPI, but i can say, that in my CoreBoot 4.15 Image from 11/09/2021 Windows 10 is booting just fine from SeaBIOS. Some time later under CoreBoot 4.16 i saw that windows is BSODing. Tried yesterday with CoreBoot 4.17 and its still broken.
I think, since CB4.16 there is something broken in ACPI. As i read, the problem is, that ACPI reserves some memory area, which in Windows is reserved for the system.
This [[https://ticket.coreboot.org/issues/327]] seems to be a similar problem, but the guy is using TianoCore instead of SeaBIOS. Changing the line OperationRegion (OPRG, SystemMemory, ASLS, 0x2000) to OperationRegion (OPRG, SystemMemory, ASLS, 0x1000) doesnt fix it for SeaBios, but fix it for TianoCore.
