[Bug 286828] [NEW] CIFS share broken after upgrade from 8.04 -> 8.10

[Steve French]

"cat /proc/fs/cifs/Stats" to see if there were any reconnections and
"cat /proc/fs/cifs/DebugData" to list the version information that the
server reports for this mount

If you can save a wireshark (or tcpdump) trace of the failure that
would be ideal and would allow diagnosing the problem quickly.  See
http://wiki.samba.org/index.php/Capture_Packets for more details on
how to do that.
