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.
Thanks,
Peter
