kernel >4.17 did NOT work.

It didn't hang while using the PC, but it did freeze when the power managem=
ent
tried to power off my both monitors. One of them was successfully powered o=
ff,
while the other showed the mouse cursor in the screen.=20

There are no system logs, as it froze so hard that not even "REISUB&qu=
ot; worked.

Again, this works OK using Radeon.


Details:
kernel 4.18.1
Ubuntu 18.04.1 + stock Mesa (no upgrades here)
Sapphire AMD GPU 390x 8GB
DVI + Display port connected. The display port actually has an adapter to g=
et
VGA, and the DVI goes straight to the 1080p dell monitor.
The monitor that worked OK when turned off was connected to the VGA adapter=
 in
the display port. The DVI port was the one that showed the mouse cursor.

Running on a Ryzen 1800X. The processor had his own stability problems a few
months ago, but a BIOS update fixed that.

The only way to get the PC to a stable state with the amd 390x is to blackl=
