Hi Matt,
Ive applied the patch but the problem persists. NFS server shares
/mnt/backup located on external usb hdd. if a NFS client mounts
/mnt/backup, and then /mnt/backup becomes unavailable, ie. the fs on the
backup drive is umounted, all processes that try to use /mnt/backup on the
client get stuck. also programs like df get stuck too, although trying to
cd into the directory is not permitted (says about nfs mount being stale)
