Bug 220075

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)

[    0.306631] 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!
