Hi Patrick, 

Thanks for your email. I did what you suggested

a) removing usb modules / patching usb.c 
With the same .config this is the output of lsmod

Now modules are
-------------------------

Module                  Size  Used by
(snd sndcore related intel, ac, seq, pcm, mixer..etc)
nls_iso8859_1           3872  1

If I patch usb.c there's no need to remove usb modules, 
and I get the same result:

echo -n mem > /sys/power/state

The only problem now is that if I suspend, when resuming, neither the
mouse nor the NIC works, but it's getting much better.


with 
echo -n disk > /sys/power/state

Stopping tasks: ===================================================================
 stopping tasks failed (1 tasks remaining)
 Restarting tasks...<6> Strange, artsd not stopped
  done

IIRC, I only have to kill artsd before hibernating...




Anyway, thanks again,

Ramon
