dmesg output

First off, I would like to thank the amdgpu developers.  I was able to boot
4.15-rc1 on my RX Vega 64 and activate six displays (using two startech MST
hubs).  Kudos!

I am however getting ~5 of these on boot:

The full text of the backtrace of each one is:

[  134.682042] ---[ end trace dcc42fd11b517234 ]---

The hardware is an RX Vega 64 on a X399 Threadripper with a 1900X CPU.  I am
running linux 4.15-rc1 with libdrm 2.4.88 and xorg-server 1.19.5.

I am happy to give additional feedback or test patches.
