Long hangtime at passphrase during reboot

Hello,

I have Arch installed with LVM on LUKS, and a separate unencrypted boot partition. The network adapter shows up missing after cold booting the computer, but gets set up properly after a reboot, similarly to what is described in https://bbs.archlinux.org/viewtopic.php?id=185765. However, during the reboot the system hangs for a long time (between 10s and 1 min or more) after I enter the passphrase. During the initial cold boot, that step usually takes 5-10 seconds.

Here is what I get after the reboot:

$ systemd-analyze

If I understand correctly, the problem is the "(kernel)" part, for which I would like to get more information.

$ journalctl -b  gives:

and here is the /etc/fstab file:

The system worked nicely (no network adapter issue, and reasonable boot time) for over a year and a half before an update this winter. I've tried fixing the network adapter issue at cold boot by changing various things in the BIOS settings without success.  Is the slow boot time related to the network adapter issue, or to the way I have my partitions set up? I am not really sure how to proceed from here. Any hint or suggestion would be appreciated.
