I have a DVD I bought today that about 80% of the way through
causes an error, 'cmd 0x28 timed out', resets ATAPI 2 or 3 times... and
then produces the Oops attached below.

	This has happened in 2.6.8-rc1-mm1+idefix2 (a mebbe 5 liner 
patch to fix LBA 48 FLUSH CACHE on non-LBA48 capable drives from
Jens. was merged into rc2-mm, possibly in rc1-mm2 or mm3), and also
2.6.9-rc4-mm1+revert_optimize-profile+undecoded_slave-fixup

	undecoded slave fixup is a oneliner patch in ide-probe to 
recognize both of my Maxtor drives that appear to have the same serial
number, D3000000. This fix was discussed a month ago or so, as I had run
into it, but nothing official came of it, and it was never merged to -mm.
Patch attached.

	Btw, the oops does not occur with another DVD I have. However, I
did go to the store and get another copy of the problematic DVD, and the
same problem occurred.
