Thanks, Jeff. I just grabbed and installed 2.6.18-128.el5.jtltest.57PAE
and didn't have any luck. The cifs mounts fail completely (even with
just one user) and tcpdump shows they aren't generating any traffic to
the samba server. I ran the mount via strace and it says it is
panicing. Here are the results:
# strace -f -v mount -t cifs //curie.cs.indiana.edu/robh /u/robh
... lots of output deleted ...
[pid 6310] write(3, "Password: ", 10Password: ) = 10

I don't see anything being syslogged when I do this. Please let me know
what else I can I do to help debug this?
Thanks!
