Can you try the attached patch and see if anything changes?
The patch _seems_ to solve my problem. I am just really astonished when
I read the diff file :D. Can I expect that it will be merged to the
official kernel sources ?
It seems that some devices choke when the bytes after CDB contain
garbage. I seem to recall that I read somewhere ATAPI device require
left command bytes cleared to zero but I can't find it anywhere now.
Maybe I'm just imagining. Anyways, yeah, I'll push it to upstream.
