I would not recommend a fedora kernel on an SMP XEON system.  I'm not 
sure about
SMP on a P4 with hyperthread enabled.  The boxes I have tried have all 
been supermicro
dual XEON with and without hyperthread enabled.  They worked well with NFS
mounts ot a remote server until I started mounting a remote samba share 
from them.  I have
tried multiple Fedora kernels and the only ones that don't crash are UP 
kernels.   I am
now using RH Enterprise on my test machines, not Fedora due to this issue.

I hope they do get a stable kernel as this looks really bad for Fedora 
since this has
been an open issue for so long (see 
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=109497)
