Cannot see SCSI CD changer in 2.6.24-14-generic or newer kernels

Greetings!
I have a 200-disc SCSI-attached CD changer that I'd like to make use of, and
I'm currently running 8.10 (upgraded from Gutsy). However, ever since
upgrading from kernel 2.6.22-14-generic to kernel 2.6.24-14-generic (and all
subsequent kernels) the boot process hangs and drops out to
initramfs/busybox while the CD changer initializes itself (i.e. it checks
all 200 element slots for discs). After around 7 minutes, I get a message
that ch0 has finished and that a SCSI disk is attached. However, I'm stuck
in initramfs.
I increased the root timeout value to 10 minutes and the system will boot,
but what then happens is I get numerous error messages from within Gnome
that I can't mount the audio disc (which is is in the changer for testing).
I'm at a loss as to how best to diagnose and resolve the situation. Any help
or suggestions would be very much appreciated!
The (truncated) dmesg output from the running 2.6.22-14-generic boot is:
