Description Blake C Lewis 2020-05-26 16:36:37 UTC

Kernel 2.6.6 - 5.6.14
AMDGPU
video corruption/noise in blocks (Chrome) and freezes (CS:GO)

HP Elite Disk 705 G4 Micro
AMD Ryzen 5 Pro 2400GE w/ Radeon Vega Graphics

How reproducible:
Chrome: youtube.com or twitch.tv blocks on the screen get corrupted.
CS:GO play for a few minutes

In kernel 5.5.17, no corruption, CS:GO works video freeze.

Additional info:
Fedora 31 and 32
All kernels v5.6 that have been delivered to FC31 and FC32, <=5.6.14 tested
The first 3 kernels v5.6 broke graphics in FC31, so I upgraded to FC32
Kernel 5.5.17 works without video corruption in FC31 and FC32

I am willing to run any data collection needed.

Please attach your xorg log (if using X) and your dmesg output.

I haven't compiled a kernel in like 15 years, I compiled in the 1 and 2 series. I will have to figure this out.

Can you try adding amdgpu.ppfeaturemask=0xffff3fff to the kernel command line in grub?  Does that help?
