DVD/ide-cd related Oops 2.6.[89]-mm

DVD/ide-cd related Oops 2.6.[89]-mm

[Tabris]

[-- Attachment #1: Type: text/plain, Size: 899 bytes --]

	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.

Did you test it on different controller (as asked by Eric)?

	Hmm. no, I had not tried that. I can probably arrange it assuming I end 
up doing any work on the DVD oops as well. Just trying to minimize 
downtime on this system.

	Patch attached with a comment. Possibly not necessary, but as it's a 
fixup, probably should anyway.

Some people only open up to tell you that they're closed.

	Any thoughts on the DVD oops? I'd like to be able to find a fix for 
this so I can actually watch the movie.

Fundamentally, there may be no basis for anything.
