Hi, Verbose kernel log and network trace would help. Take a look at: https://wiki.samba.org/index.php/Bug_Reporting#cifs.ko I understand it's annoying but having this data saves a lot of time for everyone :) If you're worried about exposing names and IPs, you can send it off-list and/or encrypted (see GPG fingerprint in my signature). Passwords don't show up in those files and assuming kerberos or NTLMSSP which is default, you shouldn't worry about the hash either at the moment.
