I get the same error on a cvsup'd stable, downloaded around 9-1-97. I can not "mount -o ro -t cd9660 /dev/worm0c /mnt" without getting a IO error. I used to be able to mount this, using the same kernel config. The drive is a HP 4020i CD writer. It is possible for me to do dd if=/dev/rworm0 of=/dev/null bs=32k and read the whole CD; don't know if I can write cd's or not with this version because I haven't tried.
