Comment 2 Dave Jones 2005-07-15 20:01:59 UTC 
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.
Comment 3 Christophe Lambert 2005-07-18 07:59:46 UTC 
After the crashes at the beginning of june, I updated the kernel to the one of
Fedora 4 and the computer is running fine since then (+/- 1 month without a
single crash).

I will install the new Fedora 3 kernel to test it.

Best Regards
Christophe
Comment 4 Dave Jones 2005-07-30 00:44:00 UTC 
As they are both based off of 2.6.12.1, I'm fairly confident this is fixed in
FC3 too. If it reoccurs, please reopen.
