Today after d-u now:
2.155s systemd-udev-settle.service
243ms keyboard-setup.service
169ms console-setup.service
120ms Modem
Compared to my initial post here in this thread, the systemd-udev-settle.service came down from 32 s to 2 s.
That looks good. Hope it stays from now on like this.
Thanks, may be it is the new kernel.
