I'll let Tejun answer that one since I don't get an oops. However, now
that I have an ide-tape hardware here, I do get something DMA-related
failing during boot:
[ 1.677012] hdb: Seagate STT8000A, ATAPI TAPE drive
..
[ 1.701097] hdb: host max PIO4 wanted PIO255(auto-tune) selected PIO4
[ 1.708289] hdb: bad DMA info in identify block
[ 1.712872] hdb: host max PIO4 wanted PIO255(auto-tune) selected PIO4
..
[ 3.450381] Uniform CD-ROM driver Revision: 3.20
[ 5.467347] ide-tape: hdb <-> ht0: Seagate STT8000A rev 5.44
[ 5.484852] ide-tape: hdb <-> ht0: 88KBps, 14*26kB buffer, 400ms tDS
and more specifically the bad DMA info in identify block thing above. I
haven't looked into it yet but its next on my TODO.

... and I'm afraid we'll have to do some serious bugfixing since this
driver is behaving really funny :). Stay tuned, I'm on it.
