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?).
