Subject2.5.64-mm2->4 hangs on contest
Date
Tried running contest on 2.5.64-mm2 and mm4 and had the same thing happen. It 
will hang reliably during process_load. I tried not running process_load but
it would still get stuck in one of the other loads (either a tar load or list
load). I can simply stop contest at that stage but then the machine wont work
well hanging at the console after a minute or so. This started at mm2
(doesn't happen with mm1).

Here is the sysrq-p and sysrq-t output during process_load (which hangs every
time):
