Output of dmesg

Description of problem:

After upgrading to F28, the system boots very slow and hangs displaying

(1 of 3) A start job is running for Monitoring of LVM2 mirrors, snapshots etc. using dmeventd or progress polling
(2 of 3) A start job is running for dev-mapper-fedora\x2dhome.device
(3 of 3) A start job is running for udev Wait for Complete Device Initialization

at the console. Further investigation via systemctl blame lead me to the "systemd-udev-settle.service" which seems to fail:

# systemctl status systemd-udev-settle
‚óŹ systemd-udev-settle.service - udev Wait for Complete Device Initialization
   Loaded: loaded (/usr/lib/systemd/system/systemd-udev-settle.service; static; vendor preset: disabled)

This happens on a standard Dell XPS with SSD, LVM and crypted disk upgraded from F27.

Version-Release number of selected component (if applicable):


How reproducible:

Every boot time.

Actual results:

I've to wait ~3 minutes until the system comes up and I can log in.

Expected results:

It's booting as quick as it did on F27. Or even faster ;-)

Additional info:

I've attached a dmesg. If there's more information I can provide, just tell me.

Comment 1 Cajus Pollmeier 2018-05-09 14:53:00 UTC
It turned out that it was a high-dpi left over udev rule that caused that.
