В dmesg строчки, вида:

[ 3809.177092] psmouse serio4: Touchpad at isa0060/serio4/input0 lost sync at byte 6

Решение:
echo 1 &gt; /sys/devices/platform/i8042/serio4/reg_07
помогает, но как-то некрасиво

Пока вижу это на p7, на обоих ветках (un-def  и std-def), но думаю и на сизифе то-же (сейчас регулярку скачаю и проверю).</thetext>

    <thetext>Проверил - на ядрах Сизифа то-же самое, и тот-же рецепт лечения. 
Повесил эту команду в rc.local.</thetext>
