I have bought a new Twinhead F10D laptop (identical to Averatec AV1050). During boot the ACPI subsystem reports these errors for all kernel versions that I have tried (extracted from dmesg): ACPI: Sleep Button (CM) [SLPB] ACPI: Power Button (CM) [PWRB] ACPI-0140: *** Error: Store into Alias - should never happen ACPI-0508: *** Error: Method execution failed [\_SB_.PCI0.IGFX._DOS] (Node c146c360), AE_AML_INTERNAL ACPI: Video Device [IGFX] (multi-head: yes rom: no post: no) ACPI: CPU0 (power states: C1[C1] C2[C2] C3[C3]) ACPI: Processor [CPU1] (supports 8 throttling states) ACPI-0140: *** Error: Store into Alias - should never happen ACPI-0508: *** Error: Method execution failed [\_TZ_.RTMP] (Node c146e400), AE_AML_INTERNAL ACPI-0508: *** Error: Method execution failed [\_TZ_.THRM._TMP] (Node c146e2e0), AE_AML_INTERNAL I guess that as a result, the directory /proc/acpi/thermal_zone is left empty. Apart from these error messages, I have not encoutered any functional problems. Do these errors point to a bug in the ACPI subsystem, or is it rather the BIOS implementation that is buggy? I'll attach additional information. If you need any more information, please let me know.

Problem reproduced from the acpidump. Seems to be an issue with the GDGS alias when executing this instruction: Method [RTMP] executing: [RTMP] @0008A #0070: Store (NVGA, \GDGS) Investigating.
Problem has been identified and will be fixed for the next release of ACPICA
Fixed in ACPICA version 20060127
Thanks for the fix. Will the new ACPICA code make it into kernel 2.6.16?
ACPICA 20050127 shipped in Linux-2.6.16-rc1-git6 -- closing.
