My computer blanks the display after couple of minutes of inactivity. When waking up the display with the keyboard, X freezes and the monitor does not have the signal. I must reboot with the power button. See the dmesg output attached. I tested with the drm-next-4.21-wip kernel compiled today and used updated Oipaf ppa Mesa. This is a regression happened in the AMD wip kernel in 3 weeks.
