I noticed that there is a branch in the linux sources “5.4.163-gti” that seems to be pretty active. While I know the documentation and build manifests for the Ultra specify a 4.19 series kernel, I was wondering how much risk there is to trying the 5.x series kernels on it. Has anyone tried this and run into problems?
The last update to the 4.19 series seems to be 15 months ago.
