Bug Description

Binary package hint: linux-image-2.6.22-14-generic

After upgrade to :
linux-image-2.6.22-14-generic 2.6.22-14.47

My system freeze (after a moment) if I try to mount a nfsv4 share with kerberos and work again when I boot on 2.6.22-10.
May be because of the last nfs security fix ?
The bug is easily reproducible if you need more info.

I've already found a fix here:
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/164231/comments/22

and once I rebuild the kernel myself it (NFSv4) started to work again. I
tested it lightly just between Ubuntu's dom0 and Solaris 10 domU.

Cheers,
Karel
