My fedora 10 laptop routinely "freezes". That means the

at the cpu consumption graph I can see that something had the processer
pegged at 100% but what? during the episode there is no way to switch
to top or the ksysguard process list because the system is
unresponsive. So how do I find out what caused the lockup?

Wendell,
There are a few options here but probably the easiest is to set top
running with a long(ish) time between updates -- something like "top -d
30". When your laptop unfreezes, go to the top window and see what's
been sucking CPU.
