I'd like to perform a kernel bisect to figure out which commit caused
this regression. We need to identify the earliest kernel that did not
exhibit the bug and the first kernel that did exhibit the bug.

Can you test the following upstream kernels and post back?

v4.4.19: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.19
v4.4.20: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.20
v4.4.21: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.21


Thanks in advance!

Title:
  4.4.0-40.60 fails to boot

Status in linux package in Ubuntu:
  Triaged
Status in linux source package in Xenial:
  Triaged

Bug description:
  I've just tried both -39 and -40 in xenial-proposed, and both fail to
  boot on my laptop (dropping to busybox - see the attached screenshot).

  This is a regression over -38, which works fine.
