crashes on "new" FC3 install

[neidorff]

Hi Folks,

I installed FC3 recently and things were running just fine.  It seems
that (although it could be a coincidence) that since I updated the
kernel via yum that, when running with a load, the system crashes. 
This seems to be happening about once a day and for no reason.  Is
there a known kernel problem or other instability with updated FC3?

Thanks for any help,

Mark
