Which makes sense in so far as I have a Barts card, but obviously this commit did not introduce the actual problem. I guess I'll have to bisect again with an explicit radeon.dpm=1 kernel parameter. FWIW, on 3.12 and earlier, I used to "echo low > /sys/class/drm/card0/device/power_profile" by means of an init script, and never had any issues with that. -- You are receiving this mail because: You are watching the assignee of the bug.
