Title:
  Ubuntu 15.10 full freeze (maybe intel hd graphics kernel failure)

Status in linux package in Ubuntu:
  Expired

Bug description:
  My new Acer ES1-411 won't work under Ubuntu. It has a Intel N3540 CPU
  and a integrated Intel HD Graphics GPU. It has a UEFI and I ran
  dualboot Windows 10 and Ubuntu 15.10. UEFI firmware is latest. While
  just working and surfing it runs, but when I look at videos (mp4) it
  takes sometimes only seconds sometimes minutes until the machine full
  freezes, no keyboard and no ssh access to it. So also no logfiles from
  the crashes exist. I still tried to change the GPU frequency with
  intel_gpu_frequency from the lowest to highest value, already switched
  off bluetooth, but no change. I also still tried the latest evaluation
  version of Ubuntu with the 4.3 kernel and the 01.org intel drivers but
  also no change. I tried 4.4.rc7 and it seemd to be better but with
  this kernel touchpad won't work.
