Are you using signatures? I've been working some with kerberos mounts
today and have found that CIFS tries to share TCP sessions between
users, but that doesn't seem to be working well with signatures
enabled (you need different signing keys, etc). You may want to try
disabling signatures and see if that works around the problem.
