Description Andy Furniss 2016-08-19 13:01:40 UTC 
R9285 since below testing amd-staging-4.6/7 I lock on boot as soon as drm loads.

No logging, no sysrq, no display, flashing keyboard.

    drm/amd/dal: track display state based on sink and stream for freesync
    
    This is to avoid problems with arrays out of bounds when OS calls
    a flip on a display that's been removed but on which reset_mode
    has not been called yet.

Current revisions of amd-staging-4.6/7  are working OK for me.
