--- Comment #10 from fin4478 at hotmail.com ---
The mainline kernel 4.19.0 from kernel.org is the best, no system freeze when
waking up from monitor sleep.

Latest mainline kernel 4.20-rc1 from kernel.org and AMD drm-next-4.21-wip
compiled at Saturday do freeze the system when waking up from monitor sleep
after 10 minutes and more.


There is ^@^@^@ garbage strings in the /var/log/messages file when the system
freezes.

My computer is always on, only my Samsung 24" S24F350H hdmi monitor  sleeps.

I have ASUS Radeon RX 570 4GB Expedition OC now.
