Description pkk 2019-11-20 12:56:24 UTC 
When I log into XFCE with a 5.x kernel on  my AMD Ryzen 5 3400G-based system, the screen turns solid dark green; it stays that way until reboot.

I see this issue on Debian GNU/Linux:

Three others see the same issue on Manjaro:

Is this a regression?  If so, can you bisect?  Please attach your xorg log (if using X) and dmesg output.

Out of the three Manjaro reports, only one is about the 3400G, the other two are about the 2400G, but the symptoms seem to be the same.

My dmesg output is at:

In 5.2, I get the green screen crash about 60% of the time when I try to log into XFCE. In 5.3 I get it nearly always.

I used an AGESA 1.0.0.3 ABBA BIOS.

I'll get the Xorg log and will check with an AGESA 1.0.0.4 B BIOS tonight or tomorrow.

Today, I've also installed a 5.1.21 kernel from Ubuntu on my Debian GNU/Linux testing system, and logged into XFCE thrice. I did not see the green screen crash with that kernel, though one I got a crash (system frozen, only mouse pointer still moveable) a few minutes after logging in.

Looks like someone has a very similar problem (green screen crash on 5.3 and 5.4 kernels on Ryzen Vega APU) with Civ 6:

I cannot reproduce the issue using kernel 5.5.
