Update: We have decided to pull back to 5.14.21 and older Xorg until both kernel and xorg are in a better state. While we recognize the 5.14 series is EOL, there is simply too many regressions across AMDGPU, Intel, and some Nvidia hardware to warrant a move to 5.15 at this time.
We will continue to re-evaluate the kernel with a smaller testing group that worked with us on identifying and looking into these regressions, and monitor relevant issues + topics on it as well.
When we are comfortable moving to a new kernel, we shall do so, and until then we will be backporting any pertinent security fixes that impact our users.
You can expect a sync this Friday (December 10th).
