It's one line of code that freezes X during start on my HP Pavilion dv7 hybrid
graphic (AMD HD 42000 - AMD HD 5400):
# git bisect visualize

drm/radeon: call hpd_irq_event on resume
commit dbb17a21c131eca94eb31136eee9a7fe5aff00d9 upstream.
Need to call this on resume if displays changes during
suspend in order to properly be notified of changes.

Removing the line inserted by this patch from 4.4.4 makes X on my laptop work again.
Just for the records: with the above patch the laptop freezes during shutdown
and has to be switched off by pressing the power button several seconds until
power-off.
Regards,
jvp.
