Interesting update. I've followed the build instructions for the Ubuntu kernel: https:/
By cloning the repo: git://kernel.
And building the kernel tagged as: Ubuntu-
Which is *older* than the last _good_ Ubuntu kernel I have (5.11.0-37) left installed from the previous version of Ubuntu (21.04, Hirsute) but the problem is *reproducible*.
This means that the issue is a combination between the configuration in Ubuntu 21.10 and some Ubuntu kernels built from the ubuntu-impish repo. I have to try building another Ubuntu kernel from the Hirsute repo and see what happens. Apparently all mainstream kernels >= 5.11 and all Ubuntu Impish kernels have this issue, when running Ubuntu 21.10 (desktop).
