Dear Scott,

unfortunately the machine is in production. Any downtime is really a 
problem since it is seen directly by our customers. I would really like 
to do some active effort to isolate the problem, but my boss would cut 
my head off, if I have to stop the machine. The firmware is not current, 
but according to Dell's web site I should stop almost every running 
service on the machine before upgrading the firmware, and in this case I 
would again have to watch out for my head. I do really care to provide 
accurate bug reports to OS projects that I use (I would guess that 90 % 
of my reports lead to a quick fix), but in this case I do have to make 
an exception and keep the machine running.
