So I've installed the kernel-default-5.16.11-lp153.2.1.g90630c5 from
Kernel:stable:Backport, but I'm having a problem when booting the system with
it.

First, the systemd-modules-load.service fails and a bit later, the boot gets
stuck at "A start job is running for /dev/disk/by-uuid/20b...395". That
20b...395 partition is my root partition with Btrfs on it. So far, I've waited
for 5 min and nothing changes.

I tried to get more info with rd.debug or loglevel=6 kernel parameters but it
doesn't say anything more on the stuck job.

I also tried to check boot log with "journalctl -b -1 -p err" when fully booted
with the stock 5.3 kernel, but the previous boot with the 5.16.11 kernel is not
seen by journalctl, probably because the root is not mounted at that time so
journald can't write to /var/log/.

I also tried to get to the shell with rd.break=pre-mount to check the failing
service and stuck job more closely but while I get the shell indeed, I'm not
able to type anything since my keyboard isn't enabled yet.

So I was fiddling around with dracut to get keyboard support at early boot, but
"dracut -f --force-drivers usbhid /boot/initrd-..." didn't help - my keyboard
is still dead.
