lockups shortly after booting in current git.

In v3.3-8839-gb5174fa I see some behaviour on my laptop
that I haven't noticed on other machines.
It boots up, I can log in, and start up a terminal, firefox, banshee
and use the system, and all is good. Then if I lock the screen,
walk away for a while and come back to it, the loadavg has sky-rocketed,
and every process is hung. Trying to run any commands that perform disk io
hang immediately.

There's a (truncated) sysrq-t output at http://codemonkey.org.uk/junk/process-trace.txt

Top showed kworker was going nuts. Trying to run perf resulted in a black screen.

anyone have any ideas ?
