I don't believe this has anything to do with the io scheduler, it looks clearly like a problem deep inside the aac driver (and thus completely io scheduler independent). The fact that it triggers with deadline is likely completely coincidental. Looks like scsicmd->scsi_done == NULL which is very odd. You may want to try and add some debug prints checking that (and dumping scsicmd state) fact. -- Jens Axboe - 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/ | ||||||||||||
