Btw, I don't actually understand why interrupt "simply lost", IMO it should not.. :-/ But this what I'm observing via bunch of printks in the code flow. Maybe there is not so obvious race, which I can't see. So, help needed. Either it is a proper fix, or it is a workaround for another bug somewhere else. -- Anton Vorontsov email: cbouatmailru@xxxxxxxxx irc://irc.freenode.net/bd2 -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
