I reported this before as well.  Blanking a CDRW on an IDE writer
and trying to mount a cdrom on an IDE reader on the slave on the
same IDE channel produces a dual oops.  I got an initial response
from Alan, and I believe Jens Axboe, and never heard about it
again.  I dunno if it was fixed or not.  It still oops's though.
