--- Comment #48 from Bjorn <bjorn.aili at gmail.com> ---
I managed to compile and test drm-next-4.17-wip, commit
a611dd16c69025b6df115427af0a5d63ae9f5145.

I can confirm that I did not see the amdgpu crash on boot any more. However,
suspend/resume still hangs my laptop.

So not sure if my suspend/resume hangs are related at all to this particular
bug, but I was hoping to get some help in figuring this out. Eg, any way I can
get some useful logging information out of a hanged session? In particular,
suspend seems to work as I can hear the fans etc turn off when I close the lid.
If I then open the lid and wait for a bit, they start up again but my screen
remains blank.
