ide-scsi oops was: 2.6.0-test4-mm3

[Mike Fedyk]

Didn't modify subject line... :(

Hi,

I have another oops for you with 2.6.0-test4-mm3-1 and ide-scsi.  I've been
using it for the last few days straight and I tried copying files from my
ide cdrom using ide-scsi.  cp segfaults, I get this oops, and X hangs.
Syslog was running long enough to capture it, and a sysrq SUB saved it to
disk.

I will be trying a newer kernel soon.  Has this been caught and fixed already?
