I've tried two workaround and in this way I made it a little better.
1) Adding some boot option in grub's menu.lst file: i8042.nomux i8042.reset
i8042.noloop
er.
2) adding the following lines to my /etc/rc.local:
for I in `ls /sys/devices/platform/i8042/*/rate` ; do
echo -n 40 > $I
done
The powertop output is:
32,5% (264,6) <interrupt> : PS/2 keyboard/mouse/touchpad
If it's necessary to do a more accurate testing please tell me what do
to.
