There have been a lot of threads about the stability of the FC1 SMP
kernel on this list. Most point to these bugzillas:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=109962
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=109497

I doubt this problem will be fixed. It's been around a long time and
there are now some shiny new toys (2.6 kernel) to distract the kernel
developers.
