--- Comment #50 from Bjorn <bjorn.aili at gmail.com> ---
That did not help. However, looking closer at my dmesg output on the 4.17-wip
branch, I see that there's actually some error loading the intel graphics
firmware. In particular, there are these lines:

[    1.806186] i915 0000:00:02.0: Direct firmware load for
i915/kbl_dmc_ver1_04.bin failed with error -2
[    1.806188] i915 0000:00:02.0: Failed to load DMC firmware
i915/kbl_dmc_ver1_04.bin. Disabling runtime power management.

This definitely seems to imply the intel card is having some power management
issue. So perhaps my problem was never with the AMD GPU at all...

In any case, the original amdgpu crash is fixed for me too, whether it impacted
my suspend/resume or not.
