Heh, I already have a patch like this pending for 2.6.14 at: http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/gregkh-01-driver/driver-link-device-and-class.patch Andrew keeps disabling it in the -mm releases due to it misbehaiving on some of his scsi devices. Perhaps he can post that oops message again so that someone here can fix it up before I add it to the main tree? thanks, greg k-h - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
