<pre>We have a report on a set of HSW workstations running our RHEL6 backported
kernel that after a number of reboots the machine doesn't finish booting.
Serial port logging shows the start of a NULL pointer dereference before the hw
goes down completely.
We haven't reproduced this upstream yet due to lack of hardware,
and we haven't tried on other vendor HSW machines yet.
So this is a heads-up and hope someone can give it a quick try, the script they
use just boots to runlevel 5 and reboots.</pre>
