It might be inevitable that I will do something dumb more often than not when testing randconfig errors from such a vast number of lines of code ... :-/ My kmod is as follows: ii kmod 29-1ubuntu1 amd64 tools for managing Linux kernel modules I thought of upgrading to 24.04 LTS, but when upgrading kmod I've lost the capacity to boot the older kernels in bisect process? Probably, it would be for the best if I had several versions of Ubuntu in multiple boot options? However, I have not yet done that ...
