Subject2.2.14 oops
I have experienced an oops with the 2.2.14 kernel that ships with Red Hat
6.2. The oops ended with something along the lines of

Aiieeee trying to kill interrupt handler
Killing swapper - not syncing

Sorry for the vagueness; this resulted in a hard freeze where I couldn't
scroll back the console to see the top of the oops nor could I take the
time to write down the oops as this is a production system that had to be
back up asap. The oops did not show up in the system log after rebooting.

I have included the uname -a output as well as dmesg from after the
reboot. Perhaps someone out there will have some idea what might have
caused the oops. (As this is a production system, I do not have the luxury
of enabling a serial console or playing around with it.)

uname -a:
Linux thought 2.2.14-5.0 #1 Tue Mar 7 21:07:39 EST 2000 i686 unknown

dmesg (after the reboot):
