requiring a hard reset:

Fixing recursive fault but reboot is needed!
The 4.1-rc1 and earlier kernels were fine.
git bisect identified the following as the first bad commit:
0f55db36d49d45b80eff0c0a2a498766016f458b is the first bad commit
commit 0f55db36d49d45b80eff0c0a2a498766016f458b
Author: Alex Deucher <[email protected]>
Date: Tue Apr 7 09:52:42 2015 -0400
drm/radeon: only mark audio as connected if the monitor supports it (v3)
Otherwise the driver may try and send audio which may confuse the
monitor.
v2: set pin to NULL if no audio
v3: avoid crash with analog encoders
