OK, well the latest one seems cleaner, on -rc3-mm1.
http://test.kernel.org/abat/30007/debug/console.log
Just has the double fault, with no NMI watchdog timeouts. Not that
it means any more to me, but still ;-) mtest01 seems to be able to
reproduce this every time, but I don't have an appropriate box here
to diagnose it with (this was a 4x Opteron inside IBM), and it's
definitely something in -mm that's not in mainline.
