dmesg_sme

Hi all,

If I turn on SME for my Ryzen 2700x CPU, I get the following error during boot:

[   19.998488] [drm:amdgpu_device_init.cold [amdgpu]] *ERROR* sw_init of IP
block <vega10_ih> failed -12
[   19.998490] amdgpu 0000:0c:00.0: amdgpu_device_ip_init failed
[   19.998492] amdgpu 0000:0c:00.0: Fatal error during GPU init
[   19.998493] [drm] amdgpu: finishing device.
[   19.998601] [drm] amdgpu: ttm finalized

I've attached the full dmesg.

I am using a Vega 64, Gentoo, Mesa/DRI* git, and kernel 5.1.x.

I can test any patches or provide any more information.

Thanks,
Sarnex
