2.6.5: Unable to handle kernel paging request at virtual address

[Justin Albstmeijer]

Hi,

Because I experienced the following problem:
(Default Fedora Core 1 SMP Kernel Hang on Dual Xeon System )
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=109497

on a DELL Poweredge 2650 (2x 2.8Ghz Xeon processors)

I started testing the 2.6 kernel by compiling a custom kernel.
Started with 2.6.4 and moved to 2.6.5 after the problem still occurred.
2.6.5 also crashed after a couple of days.
Then I tried the kernel boot options "noapic acpi=off" and the server work
fine for 10 days.
Then it started giving segmentation faults and showed this in de messages

I can still ping the server.. but nothing else.

Any suggestion.
