Subject: [REGRESSION]fan turns at highspeed after suspend2ram

Hi

I think I found a regression in 2.6.24-git. After waking up from suspend
2 ram, the fan of my laptop turns constantly at highest speed. It didn't
do this in 2.6.24.

I bisected it down to this commit:

commit c95d47a868f35cd47643d116a3c680cdaa954df8
Author: Rafael J. Wysocki <rjw@...k.pl>

    ACPI: Separate invocations of _GTS and _BFS from _PTS and _WAK

Reverting it resolves the problem for me, but I can't say if this makes
any sense.

My machine is a Zepto laptop with Intel Santa-Rosa chipset and I'm
running
a x86_64 Ubuntu Gutsy.

Mirco
