Comment 7 for bug 2048924

I think I've chased a few red herrings. here. Even on 6.5.0-25 this issue persists. The only way to prevent it is to either downgrade to the 6.2 kernel (which isn't an option considering all the security updates which it will no longer receive) OR installing the driver package from AMD.com.

This very thoroughly implicates the amdgpu driver in this kernel version
