Here's a bit of weirdness I recently found out with my mitsumi CD-ROM drive.
Setup: 486DX2/66, 20 Meg, mitsumi FX001D, NetBSD-i386-current of June 30.
Scenario:

1. get the CD-ROM that comes with the UNIX System Administration Handbook
   (Second Edition, Nemeth et al. , Prentice Hall '94).
2. mount -t cd9660 -r /dev/mcd0a /cdrom
3. cd /cdrom/sysadm
4. cat amd.tar > /dev/null

Jul  2 20:46:51 sheep /netbsd: mcd0: timeout in state 3; retrying
Jul  2 20:47:22 sheep last message repeated 2 times
Jul  2 20:47:30 sheep /netbsd: mcd0: timeout in state 3; retrying
Jul  2 20:47:38 sheep /netbsd: mcd0: timeout in state 3; giving up
Jul  2 20:47:46 sheep /netbsd: mcd0: timeout in state 3; retrying
Jul  2 20:48:02 sheep last message repeated 2 times
Jul  2 20:48:10 sheep /netbsd: mcd0: timeout in state 3; giving up

 There are other files in the same directory that give the same results.
However, other files in differnet directories don't show this behaviour.
A "copy amd.tar nul" using DOS works fine.
 Is it just me or can someone else repeat this with the same results ?
