These are excessive values. systemd-udev-settle is deprecated for a
couple of years and nothing should be using it by now.
You should check /etc/fstab for stale LVM LV's or fs UUIDs that no
longer exist on this system. The delays are consistent with something
missing. You can also get more information looking at;
# journalctl -b -o short-monotonic
And checking for large gaps in time, what was recently started right
before that gap, or right after it if there are any timeouts. But as
it is, there's not enough information to know for sure what's going on
other than, yes in fact it's taking an excessive amount of time to
start up. And I think it is a local problem because I'm not seeing it
on three systems with clean installs, and dozens of VM's, so at the
least it's not a consistent problem.
I did a new install without LVM. Booting is still slow but everything works correctly (I did not get bug 1815787). So there is some problem with my hardware. For which component do you think I should create a bug?
