Have you opened a bug against the project bugzilla (bugzilla.samba.org)? The dmesg (Linux message log) will show certain serious errors, but enabling additional cifs debugging flags can increase the debug output. Setting /proc/fs/cifs/DebugData to 1 will cause additional cifs informational messages to be logged, and setting it to 3 (“echo 3 > /proc/fs/cifs/cifsFYI”) will also log return codes from most cifs entry points to dmesg. One of the most powerful tools for analyzing networking or network filesystem problems is “Wireshark." http://wiki.samba.org/index.php/Capture_Packets shows instructions how to do wireshark captures. -- Thanks, Steve
