I've boiled it down to whether CONFIG_PREEMPT (bug happens) or 
CONFIG_PREEMPT_VOLUNTARY (bug doesn't happen) is selected.  Of course, 
changing that affects a other things like inline spinlocking.

By changing this option, I've made the bug go away in a 2.6.32 and 
2.6.37 setup where it previously happened, and I've made it appear in a 
2.6.39 setup where it previously didn't happen.


I'll be posting this on linux-omap mailing list too.  I don't have any 
other architecture to try this on, and I'm aware that the problem may 
lie in arch-dependent code (spinlock implementation?).
