I had a strange problem where my rhel-4 sytem would come to
a crawl. A critical BIOS update fixed. The system is a
IBM Think Center model 8187UN3. The BIOS update applied
to many IBM desktops.

Hey all,

I had been having a problem with FC4 locking up overnight so I tried
upgrading to FC5, but the problems have continued. Sometimes, I'll be
able to log in after a looooong delay, and running programs, but I
don't see any particular program generating load, zombie processes or
memory usage...Sometimes top reports large percentages of "wa" or "hi"
usage, but little other stuff.

Anyone have any suggestions?
