bug in 4.9.5 through 4.9.11 kernel

Greetings mighty developers :)
im reporting a bug in which the aforementioned kernels when compiled
with the AMDGPU driver fail to properly function in the presence of a
Tonga PRO card.  The driver is loaded, the cards fans then spin up to
100% and the system becomes unresponsive to ctrl+alt+del.  additionally
no graphics are displayed.  it is all sound and fury.

debug info below.  please feel free to ask for more as needed.

And 4.9.4 worked fine? If so, can you bisect between 4.9.4 and 4.9.5?
