I've got an Asus e403SA notebook with the same elan touchpad. My
experiences are different from the others. I'm on Ubuntu 15.10 with
stock 4.2.x kernel. The touchpad works as a ps/2 mouse without
multitouch and recognised as ELAN1000:xxx. With 4.3 or 4.4 kernel
everything works fine (recognision, multitouch) but after a while
(minutes, sometimes hours) the touchpad freezes.

In the syslog appears these:

Jan  5 20:55:27 darkslide-notebook kernel: [ 1531.867948] i2c_designware 808622C

Do I need to submit a new ticket or is my problem is because of the same
driver bug?
