Arg! It's still messed up. Same weird symptoms. Very slow to log in
and run commands, but usually quite reponsive when things are running.
For example, 90% of the time, a shell is responsive when I'm typing (the
other 10% of the time it's completely unresponsive for ~5 seconds). But
when I run a command like top, it takes ~30 seconds to run. Then when
top is running, it's pretty responsive 90% of the time and shows low load
averages. The only weird thing I notice in top is that I sometimes see
-0 CPU usage on some processes. Here's an example top output
when the system is screwed up:
top - 17:53:52 up 8:32, 9 users, load average: 1.39, 0.53, 0.19

Any clues in there? Any suggestions on how to debug a system that
has low load averages, plenty of free memory, but yet is unusably slow?
Thanks...

I'm pretty new to Fedora, so forgive me if I'm way off, but I would check your Xorg configuration file. While setting up the dual-video card display on FC5 that worked a week ago in FC3, I found that my xorg.conf file determined if the computer would freeze on me. Upon loading inittab, though, the computer would also freeze the keyboard and the ability to shut down by quickly pressing the power button on the tower. Fixing the problem was only a matter of reconfiguring xorg.conf, which I accomplished by:
1. Boot the computer from the first install disk, and type "linux rescue" at the prompt
2. Find your root drive in the /mnt folder, named...I forget..."sysvol" maybe
3. Remove the "/etc/X11/xorg.conf" file
4. I got tired of the bootdisk, so I changed inittab's line 18 to "id:3:initdefault:" instead of "id:5:initdefault:"
5. Reboot,
a. If you didn't change inittab, it will probably try to make a new xorg.conf file - it did for me.
b. Otherwise, you can mess around in the bash or whatever and see if it continues to freeze, and you can type "init 5" when you feel like testing the GUI.
Two other things that froze my system - my CPU was overheating without Powersaving mode, and my USB network device likes to lose connectivity and make a few things cry. Hope my problems let you think of something.
