Title:
  ELAN1000 touchpad not recognised correctly, with upstream kernel it
  recognised, but freezes randomly

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've got an ASUS E403SA notebook with Ubuntu 15.10 and kernel
  4.2.0-23-generic from default repository. The touchpad is in PS/2
  mouse emulation mode so multitouch like two-finger scrolling is not
  available.

  Dmesg output attached and xinput --list shows:

  ⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
  ⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
  ⎜   ↳ ELAN1000:00 04F3:0401                   	id=11	[slave  pointer  (2)]
  ⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
      ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
      ↳ Power Button                            	id=6	[slave  keyboard (3)]
      ↳ Video Bus                               	id=7	[slave  keyboard (3)]
      ↳ Sleep Button                            	id=8	[slave  keyboard (3)]
      ↳ USB2.0 VGA UVC WebCam                   	id=10	[slave  keyboard (3)]
      ↳ Asus WMI hotkeys                        	id=12	[slave  keyboard (3)]
      ↳ AT Translated Set 2 keyboard            	id=13	[slave  keyboard (3)]

  The correct driver merged in 4.3.x kernel so I decided to test it from
  mainline repo http://kernel.ubuntu.com/~kernel-ppa/mainline/

  With kernel 4.3.x and newer the touchpad recognised correctly and
  multitouch works. After a while (minutes, sometimes hours) the
  touchpad completely freezes with this message in syslog:
