Tejun, if this really comes from someone trying to mount the disk as UDF (which
I think we have not shown), then I don't think this will get fixed since the CD
isn't UDF. So we really have to go through all locations as specified in the
standard to find out none of them contains UDF anchor block. And some of these
locations are near the end of the disk.
When mount is used without filesystem type (or with -t auto), then it uses
libvolume_id to identify the filesystem first and then calls kernel to mount
the filesystem. Only if libvolume_id is unable to determine filesystem type, it
calls kernel to try to mount the fs one filesystem after another - it might be
good to check via vol_id utility whether libvolume_id recognizes the medium or
not (and whether it causes those IO errors or not).
BTW: I've checked and libvolume_id does not load blocks near the end of the
filesystem to identify UDF (which makes it unreliable but that's not our
problem for now).
