I've had two recent Oopses on two different 2.6.10 kernels on an SMP system. 
  The system was being used "normally" -- a web browser, a few xterms and 
text-editors, and a VNC window running on it, in addition to some services 
(apache, ssh...).  The only thing that sticks out is that this only happens 
when someone's physically in front of the box, using its kb/mouse/monitor. 
We have this system on a KVM, and we get the jumping mouse a few times a 
day, and sometimes X and/or the whole system locks up... at first I thought 
this might be a KVM problem, but with these kernel oops I'm not sure.

The attached oops reports were created by copying the oops info from 
/var/log/messages into oops.01 and oops.02, then running:

# ksymoops -K -o /lib/modules/2.6.10-1.9_FC2smp/ -m 
/boot/System.map-2.6.10-1.9_FC2smp oops.01 >ksymoops.01

# ksymoops -K -o /lib/modules/2.6.10-1.12_FC2smp/ -m 
/boot/System.map-2.6.10-1.12_FC2smp oops.02 >ksymoops.02

Please let me know if there's any other information I need to provide.
