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
