>Description:
On beginning of reset or shutdown, nfs gives "media not available error"
when using over a wireless wpa network.  Placing home directories seems to
increase likely hood of problem.  If you wait a minute or so problem
doesn't happen.  The cause is wpa_supplicant being killed before buffers
are flushed across nfs.  The simple fix is to wait a minute before using
the power button. Second fix is to type "sync" at the command line before
using the ctlaltdel or pushing the power button.  The buffers need to be
flushed via the sync command before the processes are killed in the
shutdown script.  There should be a more practical way for this problem
to be avoided.
>How-To-Repeat:
Setup wpa wireless network.  Setup nfs for home directories.  Run apps
particularly X from home area(over nfs).  Shutdown X and hit ctl-alt-del
or the power button.
