--- Comment #7 from Michel Dänzer michel@daenzer.net --- (In reply to fin4478 from comment #4)
Those stock kernels have very little new amdgpu and radeon drivers code (see diff in kernel.org), use latest drivers when you make bug reports.
There is no such requirement. Depending on the circumstances, we may ask bug reporters to try a newer kernel, but in this case it seems unlikely that the problem is kernel related.
This kernel is latest and stable: https://cgit.freedesktop.org/~agd5f/linux/?h=drm-next-4.11-wip
This is the development tree for the amdgpu/radeon drivers, with changes going into the Linux 4.11 release, which will only get its first release candidate after the final 4.10 release. I.e. it's cutting edge, *not* stable.
