Description of problem: kernel-smp-2.6.15-1.1823_FC4.i686.rpm

Machine boots up normally after install of this kernel, but has these messages
below. After a few days, the machine hangs. When I try to type something on the
console at a prompt after this happens, I can't get a prompt back. SSHing into
the machine won't work.

ICMP pings are around .2 seconds after the hang, way slower than what is
expected from a machine sitting right next to it on the same network switch.

Rebooting deletes some bad inodes and then all seems well except that, with
this kernel, the performance isn't as a good as the other ones; everything seems
a bit slower.



Version-Release number of selected component (if applicable): 
kernel-smp-2.6.15-1.1823_FC4.i686.rpm



How reproducible:
Every time

Steps to Reproduce:
1. Install kernel from testing using yum update
2. Reboot
3. Wait a few days for it to hang. No warning is noticed before it happens.
  
Actual results:
Machine hangs after a few days. Cannot type anything in at a prompt, menus
won't work, seems like the entire system is busy doing something, but not
quite.

Expected results: No problems. :-)
