Thanks for the information. The bug is unfortunately still reproductible
with BIOS version 213 so BIOS upgrade is not an improvement. After the
login to the desktop (maybe one minute after) the touchpad crashed with
the same messages.

The needed output about BIOS:

E403SA.213
09/09/2015

Bug changed to 'Confirmed'.

** Changed in: linux (Ubuntu)

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)]

      ↳ 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:
