Issue #392 has been updated by Martin Roth.
Status changed from New to Response Needed
Is this fixed now? There was a revert of the patch that caused the problem, but that was abandoned with a comment saying that another pair of patches fixed the issue. Unfortunately, one of those two patches was also abandoned with no reason given.
Revert: https://review.coreboot.org/c/coreboot/+/65501 (Abandoned)
Fix patch 1: https://review.coreboot.org/c/coreboot/+/66255 (Abandoned) Fix patch 2: https://review.coreboot.org/c/coreboot/+/66256 (Merged)
Can anyone verify whether this is still an issue or some other patch fixed it?
---------------------------------------- Bug #392: coreboot 4.17 - SeaBIOS Windows 10 BSOD "ACPI Error" https://ticket.coreboot.org/issues/392#change-1366
* Author: Pawel Radomychelski * Status: Response Needed * Priority: Normal * Category: board support * Target version: 4.17 * Start date: 2022-06-18 * Affected versions: 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.
