>Release: FreeBSD 3.3-STABLE i386
>Organization:
TDK Semiconductor
>Environment:
FreeBSD 3.3-STABLE of the 19991129 vintage with a PIONEER CD-ROM DRM-6324X
LUN-based CD-ROM changer connected via an aic SCSI controller.
>Description:
A SCSI bus timeout occurs when the driver attempts to access the
second slot in the CD changer (cd2). If the cdX devices are listed
in /etc/fstab, the machine totally wedges. If no attempt is made
to mount the cdX devices, the machine is otherwise usable.

>How-To-Repeat:
>Fix:
Adding a quirk entry to the driver fixes the problem, even though the
comments say this shouldn't be necessary.
