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
