Mark, If you issued the SG_IO ioctl with a timeout of at least 66 minutes (expressed in milliseconds) then it looks like ata_scsi_queuecmd() has a problem.
.. Mmm.. more like blk_execute_rq() perhaps. That's where the wait_for_completion(&wait) call is at. Perhaps I should change it to wait in smaller increments, so that the lockup detection doesn't trigger on it.. Doing that seems rather wasteful, though. Note that this is the ATA "SECURITY ERASE" command, which doesn't have an "immed" bit to toggle. So one must wait for it to complete. cheers -- 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
