"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.

> After upgrading from 8.04 to 8.10 (roughly one week ago, on the 23rd of Oct 08) using update-manager -d my CIFS mounts stopped working properly. I did not change any settings between them, and I have another machine on this network that is still running 8.04 and that doesn't have any problems.
