Hm, unfortunately the journal dump is incomplete again. I have no idea why

Well, what kind of timing problem do you have in mind?

So far, the only thing I can say for sure looking at the initramfs log,
is that /usr has been mounted successfully in the initramfs.

"Something" apparently causes /usr to be unmounted later on. Which part
and why that is, is not clear yet.

Do you have any (custom) init scripts in /etc/rcS.d/ which fiddle around
with mount settings, run telinit or stuff like that?

I'm running out of ideas, tbh.

If you suspect the remount service to be the cause for this, let's
output the mounts before and after
For that run
$ systemctl edit systemd-remount-fs.service

Then add
[Service]
ExecStartPre=/bin/sh -c 'echo "before rootfs remount"; findmnt'
ExecStartPost=/bin/sh -c 'echo "after rootfs remount"; findmnt'

Reboot and attach the journal log again.
