Possibly problems with the DFS code? IIRC, samba 3.0.24 was broken wrt to
some DFS code. If you're not actually using DFS referrals, you may want to
try disabling DFS on the server. See the "host msdfs" option for smb.conf.

With very recent kernels, you can also try mounting with "nodfs" but that's
probably not in your client's kernel.
