I was able to re-create this crash the other day entirely reproduceably.
If I unplug my USB apple mouse while the computer is in between sleeping
and running normally the crash condition i described occurs, namely:

Maybe there's a deadlock somewhere in the USB layer sleep code ? I
haven't tried this with other USB devices, but I plan on doing that as
so on as I get back from OLS.
