   When I try to play an audio CD with WorkMan, I get the following error in 
   /var/log/messages:

   cd0(bt0:4:0): illegal request, data = 00 00 00 00 20 00 00 00 00 00

   I realize that this may be i386-specific, but I'm not certain of it.  The 
   controller is a BusLogic BT445:

   Mar  7 17:20:56 aqua /netbsd: bt0 at isa0 port 0x330-0x333 irq 11: version 3.3, 
   async, parity, 32 mbxs
   Mar  7 17:20:56 aqua /netbsd: scsibus0 at bt0
   Mar  7 17:20:56 aqua /netbsd: bt0 targ 4 lun 0: <TOSHIBA, CD-ROM DRIVE:XM, 3332>
    SCSI1 5/cdrom removable
   Mar  7 17:20:57 aqua /netbsd: cd0 at scsibus0: drive empty

   I believe I have played audio CDs in this drive before, when it was attached 
   to an HP 9000/425T, but I'm not 100% certain.  It *does* have a headphone 
   jack on the front...

   help?

This looks very similar to the problem I'm having with my tape drive
using an Ultrastor 34f.  I sent a PR about it, but have heard nothing.
