What, exactly, does umount report? Anything in /var/log or thereabouts when
you umount? I had a problem like this when mounting one time (ok, not
exactly like but for my suggestion it is). I ran the command with strace
(ltrace -S for those so inclined) and saw that the OS in fact returned a
more informative error than was reported. I was then able to approach from a
different angle.

So, what does:

	strace -f -o /tmp/ick.txt umount /mountpoint

put in /tmp/ick.txt
