I have however have come to the conclusion that it is Automount itself
causing this problem. I also have this problem with mounting Samba Shares.
The whole client machine would lock up or either have the same error your
getting. After a few hours of trying different settings I finally went to
mounting the shares at boot time. My question would be is there certain
settings that automount supports for auto.master for cifs and nfs verses the
running Kernel.
