--- Comment #4 from Shawn Starr shawn.starr@rogers.com --- This would have worked with radeon.ko CIK, I can double check this however using same kernel, mesa/LLVM build I have currently.
There is no kernel dmesg output showing anything failed, X just locks up, cannot VT switch, mouse can move but cannot interact with the display.
I can ssh into system when this happens.
