Uppgrade from OpenSuse 11.1 to 11.2 causes Acer laptop to overheating...

[Sebastian]

Hello,
I desperately seeks help or any advice from kernel experts.
I have Acer Aspire 5315 laptop and when I updated my OpenSuse 11.1 to 
11.2 the laptop started to shut down to prevent overheat.
I noticed that no fan is running and trying and playing with sensors, 
sometimes I get information from one sensor that always says 40C, and 
sometimes also
from coretemp sensor that shows rapidly increasing temperature from 50C 
to 85-89C.

I have this problem with base and pae kernel that was attached to 
opensuse installation dvd, and later upgraded it for 2.6.33-r5 from 
OpenSuse Factory repo - results the same.
Does any expert have some suggestions?

On several message boards there are advice that flashin BIOS should 
solve the problem, but IMO it can be the only solution - Linux shouldn't 
work that way.
On the same machine i have XP and everything is OK, stable temperature 
is maintained, I also recently clean the vents from dust and other stuff.

Best regards
Sebastian Szwarc

ps. because i am not subsribed to that group could You send suggestions 
directly to my email?
thanks

First off, this seems to be ACPI-related, so added some CCs in that direction.

Second, since you decided to report the bug directly to the kernel developers,
would you be able to test non-distro kernels on your machine?

=======================================================================
As I don't have Sebastian's email address, I'm posting here.
I had a very similar problem after an openSUSE upgrade on an Acer
1501LCe laptop. At first I could not boot from the DVD, but a CD would
and compiling kernels had to be done in "powersave -l". It progressively
got worse and I was about to throw it out.
I decided to open it up a second time and have another look.
The outlet next to the CPU was blocked by an accumulation of dust which
I mistook for a foam filter the first time around.
It also seemed to be after a kernel upgrade - debated as such on the
openSUSE factory list.
I'm glad I did as it's fully back to health.
Regards
Sid.
