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 commit b36e52c44ce6728824546d8b5f05b844cede96f1 Author: Alex Deucher <[email protected]> Date: Tue Nov 24 14:32:44 2015 -0500 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. Signed-off-by: Alex Deucher <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> 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.
