Yes this would be helpful.

    # make the kernel as verbose as possible
    echo 'module cifs +p' > /sys/kernel/debug/dynamic_debug/control
    echo 'file fs/cifs/* +p' > /sys/kernel/debug/dynamic_debug/control
    echo 1 > /proc/fs/cifs/cifsFYI
    echo 1 > /sys/module/dns_resolver/parameters/debug

    # get kernel output + network trace
    dmesg --clear
    tcpdump -w trace.pcap & pid=$!
    sleep 3
    mount.cifs ....cd ... ls.. blahblah
    sleep 3
    kill $pid
    dmesg > trace.log

this should produce a trace.pcap and trace.log file.

If the server is a samba server, the /etc/samba/smb.conf would be
helpful.

Cheers,
