I installed the 4.6rc kernel and did some quick checks. I could not reproduce the issue.
However the ZFS module is missing which might be a part of the problem.
I'm using lxd containers with ZFS enabled and noticed that the crashes seem to happen
more likely when containers are started.

Aside from pulling the upstream zfs sources and building them myself are there other
ways to get the module for the RC kernels?

Title:
  Kernel is very unstable on Dell XPS15 (model 2014)

Status in linux package in Ubuntu:
  Incomplete

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
