--- Comment #10 from boombatower jimmy@boombatower.com --- I have been running a patch radeon module (the reverted commits mentioned) on 4.4.0 kernel and have not seen the issues.
See this for the specific revert patches applied: - https://build.opensuse.org/package/show/home:tiwai:bnc962535/radeon
I'd suggest that Franklin tests it since we have spoken in IRC and see the same symtoms.
