Instability after installing the xf86-video-amdgpu package
On installing the xf86-video-amdgpu
package, graphical glitches and kernel panics have been occurring. I removed the package for a few weeks and my system became stable again but due to a problem with the kernel driver and my display, I had to reinstall. After reinstalling, my system became unstable again. On one of these frequent unstable blips, graphical glitches appeared on my browser where it appeared as though tiles would not update and then it caused another app to crash until I switched back to the browser which caused it to die with SIGILL (illegal instruction). I have no logs from the kernel panics as either my system or kernel is somehow configured not to save them. My hardware is a Ryzen 5 3500U. The GPU memory is shared with the system memory (I have 12GB installed and only 10GB is visible to the OS while the other 2GB appears as VRAM).
Neofetch lines:
CPU: AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx (8) @ 2.100GHz
GPU: AMD ATI Radeon Vega Series / Radeon Vega Mobile Series
Side note: I suspect (but have little evidence to prove) that there is little to no protection on VRAM overflows as programs that cause the VRAM to overflow seem to crash or cause the system to become unstable. I can verify that the example above did not happen due to a VRAM overflow however as I had the system monitor open and could see that only 1GB of VRAM was in use.
