>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
