Hi, I'm running a machine that mounts nfs4 over a openvpn tunnel automatically on startup. I am running gutsy I just updated to the 2.6.22-14 kernel, there was no problem before. Now the machine crashes each time I try to mount my nfs4 share. What makes this bug even worse is that after the nfs4 BUG occurs, my keyboard and mouse are frozen.
