Description Brice Goglin 2005-01-24 18:10:25 UTC

Distribution: Debian Sarge
Hardware Environment: Compaq Evo N600c
Problem Description:

Following Len Brown's answer to my initial email
http://lkml.org/lkml/2005/1/24/334

There's no more ACPI working on 2.6.11-rc2-mm1.
Reverting the bk-acpi.patch makes it work.

Looks like a problem with the global lock was introduced in 20050114.  Will 
fix and release immediately.

Comment 4 Len Brown 2005-01-26 14:13:40 UTC

please test the 2.6.10 patch here: 
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release/2.6.10/acpi-20050125-2.6.10.diff.gz 
or the 2.6.11 patch here: 
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release/2.6.11/acpi-20050125-2.6.11-rc2.diff.gz

Comment 5 Brice Goglin 2005-01-26 16:20:48 UTC

Works on top of 2.6.11-rc2
(and also on top of 2.6.11-rc2-mm1 without its bk-acpi.patch).
At least fans, battery and thermal_zone are back.

I still have these on dmesg but I think it's another problem:
