Bug ID: 220075
Summary: ACPI BIOS errors on Honor Magicbook 2024 x14
(AE_ALREADY_EXISTS, AE_NOT_FOUND)
Product: ACPI
Version: 2.5
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: BIOS
Assignee: acpi_b...@kernel-bugs.osdl.org
Reporter: einh...@gmx.net
Regression: No
I encountered multiple ACPI BIOS errors during boot. These appear to be related
to incorrect or incomplete ACPI implementation in the firmware.
Here are messages from dmesg:
[ 0.300082] ACPI BIOS Error (bug): Failure creating named object [\SCMD],
AE_ALREADY_EXISTS (20240827/dsfield-637)
[ 0.300114] ACPI Warning: NsLookup: Type mismatch on SCMD (Method),
searching for (RegionField) (20240827/nsaccess-696)
[ 0.305289] ACPI BIOS Error (bug): Could not resolve symbol
[\_SB.PCI0.GP17.AZAL], AE_NOT_FOUND (20240827/dswload2-162)
[ 0.305295] ACPI Error: AE_NOT_FOUND, During name lookup/catalog
(20240827/psobject-220)
[ 0.305299] ACPI: Skipping parse of AML opcode: Scope (0x0010)
[ 0.306631] ACPI BIOS Error (bug): Could not resolve symbol
[\_SB.PCI0.GP17.AZAL], AE_NOT_FOUND (20240827/dswload2-162)
[ 0.306637] ACPI Error: AE_NOT_FOUND, During name lookup/catalog
(20240827/psobject-220)
[ 0.306640] ACPI: Skipping parse of AML opcode: Scope (0x0010)
The system does boot, but I am concerned about potential hardware or power
management issues caused by incorrect ACPI definitions.
Moreover there are flickering display glitches (flickering) from time to time
that I don't have in Windows but I don't know if the problems are related.
System details:
- Laptop: Honor Magicbook X14 Plus 2024
- BIOS Version: 1.09
- Linux distro: Ubuntu 25.04
- Kernel version: 6.14.0-15
Let me know if more logs (full dmesg etc.) are needed — I can provide them.
Thanks!
