So my question was, how was I able to build and test yesterday in a remote server? It turns out I built it with make -j40, so I missed the error message because of the parallel build, and I didn't pay attention that the output didn't display the modules_install typical output. Usually, I do my tests in an RHEL9 machine, which ships with kernel 5.14, but this time I tested in a Fedora machine, which ships kernel 5.16. And for a moment, I forgot that. So when I booted with kernel 5.16, I believed I was running my custom kernel. Luckily, v5 mainly was a squash of v4 with this port->state check added. Anyway, sorry about the typo. v6 is on the way.
