[Jikos <1339939@xxxxxxxxxxxxxxxxxx>]

I suggest to keep the bug still open for quite some time.

We all know (and my stress-testing underlines that) that this is a duct-tape and not a real fix.
I am still planning to spend some more time on this.

If you hate having this bug assigned to Intel as you believe there's not
much that you can do (which is my current understanding), please feel
free to re-assign it to me.

I'll close it either once I am completely out of crazy ideas, or I find
a reliable fix.

Thanks.

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

Status in The Linux Kernel:
  Confirmed
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.
