[Bug 180569] Kernel OOPS when mounting NFSv4 share with Kerberos 5 authentication

Sat Jan 5 14:18:30 UTC 2008

Public bug reported:

I have an NFSv4 setup with Kerberos 5 authentication that has worked
fine in Ubuntu Feisty Fawn.

On Ubuntu Gutsy, however, I get a kernel OOPS when I issue the mount
command:

mount -t nfs4 -o
sec=krb5i,proto=tcp,port=2049,soft,async,rsize=32768,wsize=32768
SERVERNAME:/ /var/nfs/SERVERNAME/home

The output in syslog:
