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

[pid  6310] write(3, "\n", 1
)           = 1

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!
