Did this just start happening after the last update, or have they never been 
reliable?  I have one box that just started crashing after the last kernel 
update but it may just be from old age instead.  If they have never been 
reliable I'd suspect bad RAM first.  I've seen cases where you had to run the 
memory test a few days to catch it.
