Hi Level1 Community,
with the recent advancements in Linux gaming (DXVK/Proton, good open source drivers for AMD GPUs) I have started to migrate my gaming over to a Linux workstation. For the most part this works amazingly well using Manjaro on a Threadripper 1950x render box with a Radeon Vega 56. (Gaming is not the primary purpose of this machine.)
However, maybe once or twice a month I see a hard crash, presumably graphics related. It only happens when a (3D accelerated) game is running; the screen displays a solid uniform color (of random hue) and the machine becomes completely unresponsive (no hotkeys, no remote shell access) until hard reset. So I assume it is GPU related.
Googling around I find old advice on disabling automatic power management. But that discussion mentioned kernel version 3.13, so I don’t think this is the same issue.
Some other discussion recommends feeding the graphics card’s two PCIE power plugs from two different PSU rails. I am not an electrical engineer, but I hesitate to try this … I am having nightmares of electrons circling around loops that were never meant to be connected.
Is this a known problem? Would it help to switch from RADV to AMDGPU? Does anybody have similar issues with Vega under Linux?
