That was a full capture of the panic.  It's too big to fit on screen and
part of it scrolls off the top.  I don't have physical access to the
server at the moment so I can't get to the serial port which would show
me the complete dump.  Need to check to see if the RAC can help.

The kernel itself is trying to dereference a null pointer from all the
panic logs I have.  The exact position seems to vary.

Yes.  It's got all the latest versions of the firmware that I can find
on the Dell support pages for the PowerEdge 1750.
