Description Felix Braun 2005-11-29 03:04:37 UTC
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),
    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)

Comment 6 Robert Moore 2006-01-25 13:26:54 UTC
Problem has been identified and will be fixed for the next release of ACPICA
Comment 7 Robert Moore 2006-01-27 14:18:02 UTC
Fixed in ACPICA version 20060127
Comment 8 Felix Braun 2006-01-31 03:51:36 UTC
Thanks for the fix. Will the new ACPICA code make it into kernel 2.6.16?
Comment 9 Len Brown 2006-02-02 14:42:59 UTC
ACPICA 20050127 shipped in Linux-2.6.16-rc1-git6 -- closing.
Comment 10 Len Brown 2006-02-02 15:03:16 UTC
20060127 that is
