Linux ACPI bug — HP OmniDesk (M02-0310) requires acpi=off to boot any modern Linux kernel

[winget_shell]

Hi HP team,

I’ve opened a BIOS/firmware support case for my HP OmniDesk (M02-0310, Product B5RQ9AA#ABA, BIOS F.08) concerning a reproducible ACPI compatibility issue.

Summary:
Every modern Linux distribution I’ve tested (Debian 13.1 “Trixie”, Fedora 43 beta, Ubuntu 24.04, Mint “Zara”, Arch, openSUSE Leap) fails to boot unless both:

acpi=off nomodeset

are set in GRUB. Without them, boot halts early with ACPI table errors like:

ACPI BIOS Error (bug): Failure creating named object [\_SB.PCI0.LPCB.EC0._Q42]
ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog
ACPI: EC: EC device not found

Using those flags allows booting, but disables all ACPI-dependent functions (sleep, power states, thermal control, etc.). I reflashed BIOS F.08, tested kernels 6.6 → 6.18, and confirmed the issue across six distributions. Windows 11 works normally, so the fault appears limited to firmware-level ACPI handling.

Request:
Please escalate to the BIOS/Firmware Engineering Team to review the DSDT/SSDT tables for Linux compatibility.

I’ll attach my formal case number once HP Support issues it so the two can be linked.

Thanks in advance to any HP staff or users who can confirm similar behavior.
