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'.
This problem is resolved for the laptop used in the original post. However, I'm
experiencing a nearly identical problem with the 2.6.11-1.1369_FC4 kernel on a
sony vaio laptop model s460. I will post dmesg, lsmod, lspci, etc. from that
machine when I get a chance.
please file a seperate bug for the other case, even if it does look similar.
(Also note that theres a 1398 kernel for FC4 out today)
Thanks for testing.
