A bug in the realtime preemption patch that manifests on your hardware.

You could try a more recent kernel that I never officially released but
many people are successfully using. You need to activate a special
"planetedge" repository to install it. Edit:
/etc/apt/sources.list.d/planetccrma.list
duplicate the line that ends in "planetcore" and replace "planetcore"
with "planetedge" in the additional line, then
apt-get update
apt-get install planetccrma-core-edge-smp
I hope to be able to release a new kernel for fc4 in the next few days.
I thought I had a good one last week and started to have recurring
crashes on evolution startup (the email client). A tentative patch was
posted on lkml and I'm trying it right now, seems to have solved _that_
problem... we'll see...
