xen boot with amdgpu module enabled

Hi,

I'm trying to boot into a linux dom0 via xen, but when the amdgpu kernel module
is loaded, the system hangs, and the graphics card's fan spins up to max speed!

To get a better idea of what was happening prior to the hang, I connected to
the machine via serial port and captured the attached boot messages which
include a kernel backtrace towards the bottom.
