kernel 2.6.8.1-mm1 ACPI bug ?

kernel 2.6.8.1-mm1 ACPI bug ?

[Maximilian Decker]

Hi all,

it seems like there is a strange ACPI related bug in the current -mm 
patch set... ?
At least with my configuration the following happens:


With vanilla kernel 2.6.7 oder 2.6.8 I get the following at bootup:

ACPI: Processor [CPU0] (supports C1 C2 C3, 8 throttling states)
ACPI: Thermal Zone [TZ1] (30 C)
ACPI: Thermal Zone [TZ2] (29 C)
ACPI: Thermal Zone [TZ3] (26 C)
cpufreq: CPU0 - ACPI performance management activated.
ACPI: (supports S0 S3 S4 S4bios S5)


With the current -mm patchset (at least with 2.6.8 rc to .1) I get the 
following:

ACPI: Processor [CPU0] (supports C1 C2 C3, 8 throttling states)
ACPI: Thermal Zone [TZ1] (16 C)
    ACPI-1133: *** Error: Method execution failed [\_TZ_.C204] (Node 
dff45e00), AE_AML_PACKAGE_LIMIT
    ACPI-1133: *** Error: Method execution failed [\_TZ_.C203] (Node 
dff45c20), AE_AML_PACKAGE_LIMIT
    ACPI-1133: *** Error: Method execution failed [\_TZ_.TZ2_._TMP] 
(Node dff46580), AE_AML_PACKAGE_LIMIT
ACPI: Thermal Zone [TZ3] (31 C)
cpufreq: CPU0 - ACPI performance management activated.
ACPI: (supports S0 S3 S4 S4bios S5)


My hardware is a HP compaq nc8000, Pentium-M.
The problem is that with the -mm kernels the CPU fan stops to work -
causing temperature to raise very high ...... :-(

Are there any known problems ?


thanks,

Maximilian

Please take stock 2.6.8.1 and apply the latest patch here:
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release/2.6.8/
and give it a go.

This will bring your kernel up to the same ACPI patch that is in the -mm
tree, but without all the other stuff in the mm tree.

If it fails, then ACPI broke.  If it works, then something in -mm broke
ACPI.

thanks,

I just tried 2.6.8.1 with the given patch, same result.
As soon as ACPI starts up, TZ2 disappears and the cpu fan stops working.

If you need further information (lspci etc.) - please let me know, thanks !
