fc5 hangs

[Jason Anderson]

David,

It sounds like something hardware-related.  Try updating your kernel
first, if you're not using the latest one.  I recently had a similar
problem that was caused by a kernel bug relating to Athlon64 X2
processors.  It's fixed now.

Have you recently added or changed your hardware?  Run 'dmesg|less' and
look near the bottom for errors.

If that's not it, take out or unplug each piece of hardware and retest
until all your peripherals are out.  If that doesn't help, find out
which video driver you are using, and try to find a temporary
alternative.  That might tell you if your video driver or card is the
problem.
