I put rt13 on an 8 socket Opetron (48 core) box, with patch enabled. It
box did NOT reproduce the hangs the 8 socket (1 node, bleh) DL980 did.

Nor did it explode running hotplug stress, but then it deadlocks before
BOOM would have happened on the DL980. kdump isn't working properly on
this box (not an rt issue, userspace), so..
