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