Description Ahmed Kamal 2007-03-21 03:52:31 EDT
Description of problem:
My laptop a toshiba satellite A105 S361, suspends to ram perfectly, it even
blinks the cute orange led light. Opening the lid, it also wakes up very
reliably, I couldn't be happier. The only problem is that after waking up, the
cooling fan is either not running, or running at a very slow speed. Resulting in
the laptop considerably overheating, until the hardware protection circuit
forcefully powers off the laptop!

Version-Release number of selected component (if applicable):
2.6.20-1.2925.fc6 (and all older fc6 kernel)

How reproducible:

Steps to Reproduce:
1.Use pm-suspend (or KDE shutdown dialog) to suspend laptop to ram
2.Open the lid to have the laptop resume
3.Watch the laptop overheat (acpi -V), a CPU intensive app (createrepo?) causes
the laptop is hard power off
Actual results:
Fan running at min speed causing overheating

Expected results:
Fan running at max speed for cooling

(This is a mass-update to all current FC6 kernel bugs in NEW state)


I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.


I am CC'ing myself to this bug, however this version of Fedora is no longer

Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.

Thanks for using Fedora!

since no information has been lodged for over 30 days.

Please re-open this bug or file a new one if you can provide the requested data,
and thanks for filing the original report!
