Hi Spaetz.  That "fix" was documented as early as comment 7 and is
discussed thoroughly throughout the 110 or so comments.  Sadly, the fix
doesn't work in Karmic any more.  Well, I'll qualify that - it works for
wired connections, but not for WIFI.  Network Manager brings WIFI
connections down internally on a shutdown signal BEFORE any
startup/shutdown script is run.

I recommend anyone still affected by this bug to use autofs to mount
their CIFS and NFS shares.  Autofs gracefully kills the connection on an
interface disconnection without triggering the dreaded "CIFS VFS server
not responding" message and subsequent 90 second delay.

I *think* that this bug is only apparent now if :
a) You're mounting remote NFS/CIFS shares by specifying them in /etc/fstab AND
b) You're using WIFI to connect to said shares and you forget to disconnect/unmount the shares before shutting down.

Correct me if I'm wrong.  I'm not sure if there's a way to update the
bug to reflect this?
