OOPS in UDF

[Norbert Kiesel]

Hi,

I just got an OOPS while copying between two loopback-mounted UDF filesystems.
One or both of the UDF file systems are corrupted (some files not readable by
root), but kernel should not OOPS anyway.

I get the corrupted file systems reliably by rsync'ing big directories onto the
UDF filesystem (while trying to prepare a backup DVD).  I saw the OOPS only once
so far.  The system continued to work after the OOPS.

This happens on an old AMD K7 system running Debian unstable, but with self-
compiled vanilla kernel 2.6.16.19 (compiled with gcc version 4.0.4 20060507
(prerelease) (Debian 4.0.3-3)).

Best,
  Norbert
