Hi,
Recently I have noticed that one of our Dell PE1950's has been crashing
a lot with the following reason "supervisor read, page not present".
The system runs 6.2 Release under i386.
I have attached 2 back traces, and I still have both cores if any more
information is required. Any light that can be shed on this problem
would be greatly appreciated.
Tom
