I can definitely do that if that's your preferred course of action.

This will mean that smaller number of people will be hitting the bug and
hence being available to test proper fixes (hopefully the dmesg from
comment #89 will provoke some idea?).

OTOH, I will always be here to test any patches to have a final fix, so
if that's enough for you, then fine :)

Title:
  [Lenovo ThinkPad T400] intel graphics fail after suspend with 3.16
  kernel

Status in The Linux Kernel:
  Incomplete
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After resuming from suspend, I find gnome-shell has crashed. If I try
  to restart gnome-shell or gdm after this all I get is the following
  message. Everything does work fine on initial boot up until I suspend.

  intel_do_flush_locked failed: Invalid argument

  Booting on the 3.13 kernel from trusty, this problem does not occur.

  I also tried to test utopic dailly Ubuntu GNOME, this fails to even
  boot too gdm, unless I set nomodeset from the kernel line. I have
  never need to do this in the past though.
