Hello all.  I just upgraded from 2.1.6 to 2.2 and the Teac CD-56s
cd-rom drive I have is no longer working.  It worked out of the
box with 2.1.6 (under the generic kernel and under a custom built
one.  Here are the messages (lines wrapped)relating to the Adaptec 
3940 card I use:

As you can see, I get "Unexpected busfree" when it is scanning the LUN 
the cd-rom drive is on.  Any suggestions?
