What is kernel version?
What is symptom?

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.
