I think it is reliable, you just need to wait it out. The rebuilding of
akmod is being done for a given kernel while that kernel is running, so
when you update the kernel, the akmod doesn't get built until you boot
into it. And when you boot into it, systemd will at some point try to
activate the akmod, find out that it doesn't exist, fail, and initiate
a rebuild.

The rebuild takes some minutes to complete, after which it will write
out something like:

    Please wait, this may take some time...
    Done.

// I never figured why the first line isn't written *before* the
build starts, but only after it finished, when it is completely
useless... //

Once the modules have been rebuilt, the boot will continue. Subsequent
boots (for that kernel) will not require a rebuild and will be
regularly short.

HTH, :-)
