Ever since I built the GENERIC kernel and only enabled SMP and gdb (not
disabling anything ) this kernel has not crashed  : )

I did upgrade the firmware on the Integrated RAID controller at the same
time because I was simply out of troubleshooting time  : (

Well so far so good :) (uptime 3 days)

I did get this one stuck apache process (this machine is not even a web
server so I don't really care that much)

root at govmail ~ # ps wwwaux | grep httpd
www         344  0.0  3.1 24500 15884  ??  R    Thu07PM   0:37.99
/usr/local/sbin/httpd -DSSL

but when I tried to kill it with kill -9 it refused to die.  So I
rebooted the machine and it got stuck on power down waiting for the
second CPU to do "something" Sorry I didn't write it down.

So, I had to drive to the machine (an hour away) and manually reset it.

Anyway, it has been back up for 8 days, 8 hours, 14 minutes and I think 
the worst is over.

I forgot to mention I have two of these Dell PowerEdge 440 boxes running
4.9-STABLE and they are doing just fine!
(Both high traffic web+ servers)
