[Bug 36329] kernel faults during reboot

[Kipp Hickman]

Public bug reported:
https://launchpad.net/malone/bugs/36329

Affects: linux-meta linux-image-2.6-amd64-generic (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
When running the 2.6.10-6 series of kernels on my amd64 K8N-E based
system, the system will often hang during reboot because many of the
processes attempting to shut down are being killed due to page fault
errors. Typically when this happens (which is very often) multiple
programs will be crashing during the shut down.When I boot the 2.6.10-5
kernel these crashes do not happen.

Here is an example snipped from the system log:
