Has this always happened, or did it appear with recent kernels?
Comment 5 Tim Lauridsen 2008-11-11 01:04:33 EST
The laptop is new, i got it 3 weeks ago, and has only be running rawhide, becuse it need iwlagn to make the wireless work.
So it has happened it the latest couple of weeks rawhide kernels.
the /var/log/messages filled up a 20 GB root filesystem i a couple of weeks, because of these messages.
Comment 6 Bug Zapper 2008-11-26 00:06:59 EST
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

looks a lot like this one
Comment 8 NM 2009-09-04 09:07:23 EDT
Same problem on TOSHIBA Satellite M500-ST6421 laptop running freshly installed FC11 kernel CPU heats up to 99C. Fan works strongly for a second and stops. Is there any way to make it work more often or constantly at a lower speed? Are those problems related?
Comment 9 Bug Zapper 2009-11-18 03:48:58 EST
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '10'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 10's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 10 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
Comment 10 Bug Zapper 2009-12-18 01:48:17 EST
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
