Comment 5 for bug 1906729

Ok. Here are the files, and here was my process:

Followed instructions, but before hard reboot (after system has been woken
to a black screen)

* Bluetooth connected. It does not always do so.
* I switched login terminals (ctrl-alt-f2/f3) and then back to the
graphical one (ctrl-alt-f1).
  * This "worked", since I again heard bluetooth connect/disconnect
appropriately.
  * This *didn't* work, since I still have a black screen.
* I shutdown the system cleanly via an SSH call.

Still, regular suspend and suspend-then-hibernate works fine.

So, decent chance this is a graphics driver bug or a race condition.

Files included. kernel.log Lines 1381-1383 may be particularly relevant.
