NFS mount hangs

[Joshua Miller]

What is the timeout on your autofs mounts?  I typically set the timeout
to 30 seconds to prevent any lockups such as you describe.

/etc/auto.master
    /home   /etc/auto.home  --timeout=30 --ghost

/etc/auto.home
    *       -fstype=nfs,rw,hard,intr,nosuid         <nfs host>:/home/&
