Screen shows:

starting version 240
ERROR: device 'UUID=xxxxxx' not found. Skipping fsck.
mount: /new_root: can't find UUID=xxxxx.
You are now being dropped into an emergency shell.
sh: can't access tty: job control turned off
[rootfs ]#

At first I thought it was caused by linux kernel, and I downgrade it.

[2019-01-10 11:18] [ALPM] downgraded linux (4.20.arch1-1 -> 4.19.10.arch1-1)

Then I tried reinstall 'systemd libsystemd systemd-sysvcompat' and regenerate initramfs
via 'mkinitcpio -p linux'

Tried switch to LABEL instead of UUID, the error changed to:

starting version 240
ERROR: device '/dev/sda1' not found. Skipping fsck.
mount: /new_root: no filesystem type specified.
You are now being dropped into an emergency shell.
sh: can't access tty: job control turned off
[rootfs ]#

Finally, I downgrade systemd to previous version:

[2019-01-10 11:37] [ALPM] downgraded libsystemd (240.0-3 -> 239.303-1)
[2019-01-10 11:37] [ALPM] downgraded systemd (240.0-3 -> 239.303-1)
[2019-01-10 11:37] [ALPM] downgraded systemd-sysvcompat (240.0-3 -> 239.303-1)

It boots, hooray!

Same happens here just like you said!
My screen also shows
[Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0xb000020 (or later)
initramfs unpacking failed: junk in compressed archive

After that I also get dropped into an emergency root shell but my keyboard is unresponsive.

I am also affected by this bug. I have updated 3 systems since yesterday and none of them was runnable after the update.

To solve the problem temporally, I add all modules that were loaded by a live usb-stick to the mkinitcpio.conf.
After that, the systems could find the root partition.

I'm marking this as a dupe of  FS#61328  because there seems to be a more general problem of udev still not properly recognizing hardware in the initramfs, which might be related to module probing.
