Problem loopmounting CD on 2.6.0

[Niels Elgaard Larsen]

A similar (probably the same) problem have been reported for cryptoloop.
With a ISO9660 CD (actually Knoppix) in drive /dev/hdc, no SCSI emulation:

amigos20:/mnt# losetup /dev/loop5 /dev/hdc
amigos20:/mnt# mount -r /dev/loop5 /mnt/foo

Gives kernel output:

===
hdc: cdrom_read_intr: data underrun (2 blocks)
end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=loop5, iso_blknum=16, block=32
===

It works in 2.4.20

Also

dd if=/dev/hdc of=/tmp/foo
losetup /dev/loop5 /tmp/foo
mount -r /dev/loop5 /mnt/foo

works
