Hi,

When my networking card died yesterday (sundance based d-link card) i
used dhclient to update the route. Unfortunately it caused it to change
ip, thus today i had some NFS problems...

fstab entry:
blue:/mnt/large /mnt/large nfs
user,async,soft,rsize=32768,wsize=32768,tcp 0 0

Anyways, i did a bunch of umount -f's and so on and so forth as i have
done a million times before, but when i tried remounting it, nothing
happened... A quick ps aux |grep revealed:

root 26793 0.0 0.0 1740 696 ? D 14:23 0:00
/bin/umount /mnt/large
root 26800 0.0 0.0 1868 828 ? D 14:23 0:00
/bin/mount /mnt/large
root 26805 0.0 0.0 1868 828 ? D 14:23 0:00
/bin/mount /mnt/large
root 26807 0.0 0.0 1868 828 ? D 14:23 0:00
/bin/mount /mnt/large
root 26809 0.0 0.0 1868 828 ? D 14:23 0:00
/bin/mount /mnt/large

And to further my agony a dmesg revealed:

This is, as stated before, just FYI... Anyone feeling like making nvidia
comments can read this and just skip mailing "/me no care".

Hello Ian,

This looks very much like the problem in iget() I described today in
LKML. Hope I'll post a patch here soon.
