>Release: 4.0-current
>Organization:
private FreeBSD site - Arnhem - The Netherlands
>Environment:
4.0-current / Pioneer DRM604X SCSI cdchanger w/ firmware
rev 2401
>Description:
Certain Pioneer SCSI cd changers do not return the standard ASC
codes during device probe. This makes the probe drop the device,
making it unusable under FreeBSD.
>How-To-Repeat:
You just need the right Pioneer f/w & device. No further
special environment is needed.
>Fix:
Apply the following patch to /sys/cam/scsi/scsi_cd.c
