I don't see a 82371 on this board. Rather, it has a FW82801AA.

Here is the file system table (I shortened the hda1 line to fit):
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/hda1 / ext3 defaults,errors=remount-ro 0 1
/dev/hda5 none swap sw 0 0
/dev/hdc /media/cdrom0 iso9660 ro,user,noauto 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto 0 0
I'm surprised it says noauto for the CD and floppy, since I installed autofs
(another attempt to get the CD to work). Since I never did set it up,
that's probably why.
First, try the obvious: put in a CD and hit the cdrom icon inside My
Computer on the gnome desktop. The CD is the Knoppix 3.9 CD that I can boot
and run on this same hardware. Gnome says it's trying to mount the CD, CD
spins up then gnome gives the following errors:
hdc: media error (bad sector): status=0x51 { DriveReady SeekCompleteError }
hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16
hdc: media error (bad sector): status=0x51 { DriveReady SeekCompleteError }
hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16
Next, try to mount CD using mount point name. CD spins up and gives the
following errors:
sethg@cray4:~$ mount /media/cdrom0
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
sethg@cray4:~$ dmesg|tail
hdc: media error (bad sector): status=0x51 { DriveReady SeekCompleteError }
hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16

ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16
Next, try to mount CD using device name. CD spins up and gives the same
errors.
sethg@cray4:~$ mount /dev/hdc
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
sethg@cray4:~$ dmesg|tail
hdc: media error (bad sector): status=0x51 { DriveReady SeekCompleteError }
hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16
hdc: media error (bad sector): status=0x51 { DriveReady SeekCompleteError }
hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16
Finally, try an explicit mount as root. CD spins up and generates the same
errors.
cray4:/home/sethg# mount -t iso9660 /dev/hdc /media/cdrom0
mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
cray4:/home/sethg# dmesg|tail
hdc: media error (bad sector): status=0x51 { DriveReady SeekCompleteError }
hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16
hdc: media error (bad sector): status=0x51 { DriveReady SeekCompleteError }
hdc: media error (bad sector): error=0x30 { LastFailedSense=0x03 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16
It tries, but it really doesn't want to mount. Your hypothesis of an extra
driver that interferes is reasonable.
