A new version is currently uploading to rsync.rsbac.org, which contains 
several changes in the auto-mounting code. Rob, could you please retry 
with this new code? I still cannot reproduce the lockups, but the messages 
above have disappeared.

If you need PaX, too, please patch it in afterwards and use the mm/mmap.c 
file from my prepatched 2.6.6 tree.

Amon.
