mce hardware error while playing games

Brief summary of the problem:

While playing game, I have random mce hardware error, which cause hard reboots.

Hardware description:

• CPU: AMD Ryzen 5 3600 6-Core
• GPU: AMD Radeon RX 5700 XT (NAVI10, DRM 3.40.0, 5.10.7-3-MANJARO, LLVM 11.0.1)
• System Memory: 16 Go
• Display(s): 1920x1080 144 Hz (display port) + 1280x1024 75 Hz (HDMI)

System infomration:

• Distro name and Version: Manjaro Linux
• Kernel version: 5.10.7-3-MANJARO
• AMD package version: Mesa 20.3.3

How to reproduce the issue:

The best way to reproduce the problem is to play Boneworks (VR game). The issue happens almost 100% of the time, when I reach the main menu. I am using a Valve Index.

It happens in other VR games like Half-Life Alyx, but I also experienced it in the Witcher 3 (non VR). But with those games it is really random. Sometime no problem playing two hours straight, but sometimes it happens approximately once every hour.

Here is a short list of games where it happened :

• Witcher 3
• Half-Life Alyx (native Linux version)
• Moss
• Skyrim VR
• Boneworks Maybe others but I am not sure.

This is also the computer I use for my daily work as a PHP developer. The mce error happens only in game, never in other situation.
