Title:
  Random Kernel Panic with Positivo W940TU-TV laptop (Intel ValleyView
  hardware)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I'm having problem with random kernel panic with Intel ValleyView
  hardware.

  I've already test with kernel 3.16, same issue. Tried
  intel_pstate=disable, same issue.

  It does not seems to be a hardware problem, since windows 8.1 works
  very well.
