Hello,
Upon trying to mount a CD-RW I get the following error:
ide-scsi: hdc: unsupported command in request queue (0)
end_request: I/O error, dev 16:01 (hdc), sector 64
isofs_read_super: bread failed, dev=16:01, iso_blknum=16, block=32
mount: wrong fs type, bad option, bad superblock on /dev/hdc1,
Note that I use the hdd=ide-scsi parameter and that the CD is detected as
SCSI:
hdc: CD-W54E, ATAPI CD/DVD-ROM drive
SCSI subsystem driver Revision: 1.00
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
Vendor: TEAC Model: CD-W54E Rev: 1.1B
Type: CD-ROM ANSI SCSI revision: 02
Attached is my .config
Also note that the cdwriter worked fine with 2.4.8.
Please advise.

You are trying to mount /dev/hdc and that is handled by ide-scsi. Mount
/dev/sr0 instead. For that you must also remember to configure SCSI
CD-ROM support, which you haven't done:
# CONFIG_BLK_DEV_SR is not set

That config was after several attempts of getting a functional kernel in
that aspect.
With CONFIG_BLK_DEV_SR=y, the same result. Also note that mount/cat/etc.
on hdc _should_ work, but it fails both there and on /dev/sg0, etc.

A failed attempt :-)

No it should not, not if you are passing control to ide-scsi. /dev/sg0
is the sg char device, you cannot mount that. Look at your messages:
ide-scsi: hdc: unsupported command in request queue (0)
end_request: I/O error, dev 16:01 (hdc), sector 64
isofs_read_super: bread failed, dev=16:01, iso_blknum=16, block=32
mount: wrong fs type, bad option, bad superblock on /dev/hdc1,
You are mounting major 16h (22, hdc), not /dev/scd0. This is a user
error, not a bug.

try mount /dev/scd0 (not /dev/sg0) It works for me
