[Bug 601142] [NEW] maverick kernel panic on IBM System x3650 M2 and System x3250 M3

[Ronald McCollam]

Public bug reported:

I am getting a kernel panic when booting after installing the 20100702
amd64 ubuntu-server image on two systems, an IBM System x3650 M2 and a
System x3250 M3.

Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: ffffffffa0089248
Pid: 972, comm: udev_resource Not tainted 2.6.35-6-generic #9Ubuntu
Call Trace:

(See attached screenshot.)

These systems are in a Canonical testing lab and can be wiped and
reinstalled as needed.  Please let me know if I can provide additional
information.
