[Bug 1580943] Re: Kernel is very unstable on Dell XPS15 (model 2014)


Short update, I built the zfs module and tools myself. If I cannot crash
the kernel now anymore we can consider it to be fixed in upstream. Will
give a update at the end of the week.

  Kernel is very unstable on Dell XPS15 (model 2014)

Status in linux package in Ubuntu:

Bug description:
  The system is halted on my machine in different scenarios:

  1) Running debootstrap, the oops happens when chroot tries to mount a kernel filesystem from the host
  2) Running ubuntu-emulator create from the Ubuntu SDK IDE: http://pastebin.ubuntu.com/16373613/

  3) USB devices are disconnected sometimes, they are immediately
  reconnected but when a ubuntu phone is attached chances are high the
  system might hang as well

  I will attach more logs as soon as I hit the problem again
