Two days in a row my fc5 computer has frozen soon after I start using it in the morning.
[snip]
However, I have more information about the problem. I think I misdiagnosed the problem... it appears that the mouse/keyboard are not completely unresponsive... they're are just responding extremely slowly. I ssh'd into my work computer (the one that is "hanging" every day) from home last night. This morning before I came to work, I tried to do a little work from my ssh session. And it was messed up too! Things were running very slowly.

My fc5 system hasn't "hung" in 5 days, so I'm hoping that something that I've tried has fixed it.
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 Tasks: 149 total, 2 running, 144 sleeping, 2 stopped, 1 zombie Cpu(s): 0.0% us, 0.0% sy, 0.0% ni, 0.0% id, 0.0% wa, 0.0% hi, 0.0% si, 0.0% st Mem: 2067636k total, 1185580k used, 882056k free, 47392k buffers Swap: 6144820k total, 0k used, 6144820k free, 661912k cached

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...
