The babble is a separate problem. This e-mail thread is in response to Greg's finding that he could not read a partition table on a disk. This only happens with your patch applied.
The babble happens with a tape drive on read. I haven't had a chance to
test it with your patch, only without. I'm suspecting that st.ko is doing
something bad in that case.
