Re: [PATCH v2 0/3] hp-bioscfg: fix attribute enumeration on older HP BIOS

Hi,

I am writing in relation to the discussion:

[PATCH v2 0/3] hp-bioscfg: fix attribute enumeration on older HP BIOS

Message-ID: <[email protected]>

I am seeing the same AE_AML_BUFFER_LIMIT / WQBE / hp_bioscfg error 0x3
pattern on a recent HP platform:

HP Laptop 15-fc0xxx
AMD Ryzen 7 7730U
BIOS F.25, 04/20/2026
Operating system: Linux Mint
Kernel: Linux 7.2

Loading the upstream hp_bioscfg driver produces:

ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Index (0x32) is beyond end
of object (length 0x32)

followed by:

ACPI Error: Aborting method \_SB.WMID.WQBZ
ACPI Error: Aborting method \_SB.WMID.WQBE
hp_bioscfg: Returned error 0x3, "Invalid command value/Feature not supported"

ACPICA tracing of \_SB.WMID.WQBZ shows the failure with:

Arg0 = 0
Local5 = 0x32

I thought this might be useful because this system is running a
current 2026 HP BIOS, so the issue may not be limited to older HP
firmware.

Regards,

Luigi
