When I clear bit 7 I get the following now:
Jun 14 07:58:18 trainwreck kernel: drmn0: fence driver on ring 10 use gpu addr 0x00000000400000b0, cpu addr 0x0xfffff800bd4320b0

Jun 14 07:58:19 trainwreck kernel: drmn0: SMU check loaded firmware failed, expecting 0x17f, getting 0x0[drm:0xffffffff826d4dc4s] *ERROR* amdgpu: smc start failed

Jun 14 07:58:19 trainwreck kernel: drmn0: amdgpu_init failed
Which is hard to correlate without spending a lot more quality time with the driver than I've had time for yet.
One thing that occurs to me is that Linux is usually compiled with gcc6 - has amdgpu ever been tested as compiled with clang?
Below is a list of the warnings I have to disable in order to get amdgpu to compile without disabling Werror altogether. The -Wno-format is an artifact of clang or FreeBSD treating long long and uint64_t as distinct types and the -Wno-pointer-arith is to accept the linux convention of doing pointer arithmetic on void pointers. All the others are arguably oversights in the code (similar silencing has to be done in i915, but I've had better luck with it to date). I haven't fixed the warnings because I try to treat it as vendor code and minimize any local changes. Will you accept quasi-cosmetic patches from other operating systems / compilers?
Thanks.

The driver is essentially unmodified from what is found in Linux 4.6 - relying on an extended version of FreeBSD's linuxkpi shims. The shims work well enough that i915/drm from 4.6 works extremely well on most hardware (I have yet to diagnose / fix the severe artifacts on Cherry Trail and Atom).
