--- Comment #16 from Jean Delvare (jdelvare@suse.de) --- I tested Alex's branch amd-staging-4.11 as of yesterday (top commit c285c73f2213) and it does NOT fix the bug.
Did it occur to you that there may be a simple bug in commit c7bc82efa60d ("drm/amdgpu: update tile table for oland/hainan")? Can anyone familiar with the code review this commit to see if we missed something obvious?
