Description of problem:
My system was totally wedged this morning.  The last entry in my
/var/log/messages was this:

Dec  6 05:42:04 allhats crond(pam_unix)[1032]: session closed for user
Dec  6 05:44:22 allhats kernel: ------------[ cut here ]------------
Dec  6 05:44:22 allhats kernel: kernel BUG at kernel/exit.c:842!

Dec  6 06:37:41 allhats syslogd 1.4.1: restart.

Note that 5:44 is around about the time that the jobs in
/etc/cron.daily usually run.

upgrading the kernel.

Comment 2 Dave Jones 2005-07-15 16:06:44 EDT
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.
