-acX use special stack for hardware IRQs, and preempt_count() is copied only from task -> hwirq, not other way around (because of it assumes that preempt_count() is same on exit as it was on enter...). That's probably reason why -acX was working for me almost two weeks, but as soon as I returned back to non-ac, it died. Petr Vandrovec vandrove@vc.cvut.cz
