Hi Thorsten,

If you still run into this problem, could you provide a network trace
and kernel output?

     # 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.
