The unknown phase warning appears to be harmless, at least in my
experience.  It seems to be unrelated to the real problem, the one for
which you get "atapi_exec_cmd failed"

Try adding: options         ACD_DEBUG
to your kernel's conf file, and recompile.  For whatever reason (probably
having something to do with timing), I can only get it to work with
ACD_DEBUG defined.  
[Actually, I narrowed down to the printf("acd: acdstart\n"); in acdstart()]


This problem was discussed semi-recently in port-i386 - you might want to
check the mailing list archives for more info.
