Yes, kernel is different. I'm more reserved in this regard. I usually track the drm-fixes (~airlied) branch which most of the time means that it at least somehow works. Yet I make sure to have at least one additional kernel installed that I can boot into if the drm-fixes branch breaks for me.
No announcement yet.
