Just realasing a lock > which is not currently acquired should not hang the system? Hm... A simple grep over the code showed that note_interrupt is called w/o desc->lock in all places but __do_IRQ(). And this looks like an error at least for the following reason: note_interrupt() calls __report_bad_irq() and __report_bad_irq() does require desc->lock to be held. So I suppose that we have to do spin_lock(&desc->lock) before calling note_interrupt(). I'll prepare a patch in a moment. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
