Hi,

enabling traceSMB just does a hexdump of every packet sent on the
wire. You probably want this:

    echo 1 > /proc/fs/cifs/cifsFYI
    echo 'module cifs +p' > /sys/kernel/debug/dynamic_debug/control
    echo 'file fs/cifs/* +p' > /sys/kernel/debug/dynamic_debug/control

with CONFIG_CIFS_DEBUG, CONFIG_CIFS_DEBUG2, CONFIG_DYNAMIC_DEBUG enabled.

As you said it seems the server keeps reseting the tcp connexion. A full
trace starting from the initial mount will help.

You should be able to open a bug on either samba on the kernel
bugtracker and attach traces there.

Have you tried to mount using a newer protocol (2.1 or 3.0)? (using
e.g. -o vers=2.1)

Cheers,
