Ubuntu - GPU - AMD GPU - Crashes the System

It seems GPU drivers from AMD are not great.

What has worked to prevent this is the following.

Before running this I the system always crashed with the 5700 xt GPU when trying to benchmark the Heaven GPU test.

Add the following to the /etc/environment file.

# Disable all hardware acceleration in Firefox, since OpenGL is causing crashing on Navi, WebGL is the culprit.
#AMD_DEBUG="nongg,nodma"
AMD_DEBUG="nongg nodma"
#AMD_DEBUG=nodma
#AMD_DEBUG="nongg"
#AMD_DEBUG=zerovram

NOTE: Some sites say to use various variations of the above, but the uncommitted entry works for me.

Add amdgpu.noretry=0 to the GRUB_CMDLINE_LINUX_DEFAULT option:

/etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.noretry=0"

Then run:

sudo update-grub

Then reboot.

Try:

sudo sh -c 'echo "high" > /sys/class/drm/card0/device/power_dpm_force_performance_level'
