Mounting unavailable NFS shares crashes the system.

Thanks for taking the time to report this bug and helping to make Ubuntu better. With which version of Ubuntu did you notice this issue? Additionally how did you go about mounting this NFS directory? If it is automounted could you please add the contents of your '/etc/fstab'? Thanks in advance.

Hello, i'm more than happy to help and will try to answer any questions.
I'm using a fully patched Ubuntu Feisty 32bit. Not much out of the ordinary,
but i usually use Beryl.
I tried 3 different ways to mount the drive (which was unavailable at the
time of connection, but was still shown as mountable in disk mounter
applet).

First i tried it with the disk mounter applet. The result was a crash of the
bottom-panel, i could still log out of the session and log back in, no more
problems.
Then i tried the places menu, to just open the folder directly. This time
both panels crashed and i was unable to log out of gnome. I switched to the
terminal, and you know the rest.
Finally i tried to mount the drive by terminal which told me, that it was
unavailable.

The drive is in the fstab:
192.168.15.102:/home/<user>/sharing /media/<user>/ nfs
defaults,user 00
That's the only network drive I regularly use.

I've already had some trouble with the panel though. Some of the applets
crashed at login for some time. I deleted some ghost-configfiles then and
everything worked fine again.
If you need anymore infos just let me know.
Thanks for the work.

Hello once more.
I just played around the issue a bit and it seems it shows up after the
mounted nfs drive goes offline.
This is the case at the moment, and I think I'll just post the
terminaloutput:

*here the cursor blinked on like normal and nothing more happened*

In Gnome the drive still appears online and mounted and when i try to
open it, the mentioned crash of the panel and soon afterwards the
system.
Hope i could be of use.

Is there anything in 'dmesg' or '/var/log/messages' after this happens?
