@wnd:
I have built a new sd 256 preempted kernel. In this one I have modified the touchscreen driver adding checks to avoid mouse-up events in faulty hardware (only N810), finally solving the issue for me.
Could you please check if it works fine for you?
For the n800 people here, I also have changed the mouse-up event rate to a max of 10/s, hopefully solving the repeated keys problem for everyone.
The kernel is here: https://garage.maemo.org/frs/downloa...mpt-256.tar.gz
