Preventing filesystem from locking up when automount NFS share from VM goes away
I've found that umount-ing the share will also resolve the problem each time I suspend my VM.

It's not a perfect solution, as it has to be done manually, but it does work.

E.g.:


sudo umount /vhosts
(suspend VM)
sudo automount -vc


I haven't tested whether step 3 is necessary, but I figure it couldn't hurt.
