[SOLVED] "modules.devname not found" - Unbootable after update to 4.19

After running pacman -Syu, xfce crashed to an unresponsive command line and I cut off power to reboot. After reboot, the laptop boots into an unresponsive terminal with the following text:

Additional errors with ACPI on

...

When booting from the Arch ISO I can still access my files and a dd backup completed without errors. Running lspci makes the system unresponsive with ACPI error messages, so I booted with acpi=off. After that lspci works and wifi too, so I ran pacman -Syu again, which didn't change my problem. My laptop keyboard doesn't cause output any more after the update, but a USB keyboard works. When running startxfce4 as root after chroot to my disk (/dev/nvme0n1p2) I get an unresponsive GUI dialog:

Unable to contact settings server 
Unable to connect to socket /run/user/0/bus: No such file or directory

And when changing to my user with su - jo and running startxfce4, I get the following errors.

What steps could I try to get xfce4 to start and hopefully also be able to boot from disk again?

pacman log from running pacman -Syu yesterday and today. Note that yesterday the kernel got updated 4.18 -> 4.19, whereas acpid only got updated today after the problems appeared.

Looks like a mismatched initramfs. Regenerate it.

Thanks for the quick reply! I ran

mkinitcpio -k 14.9.2-arch1-1-ARCH -g /boot/initramfs-linux.img

, which successfully created a new image file, but I still get the same issues after a reboot. The Arch ISO on my USB drive (and therefore shown in uname -a) is 4.18.16-arch1-1-ARCH.

14.9.2-arch1-1-ARCH isn't the kernel you're booting, even accounting for the typo

Everything works again! You were right about the kernel version, I forgot that I had set up a separate partition for that. I'm overjoyed that you could find the solution so quickly, thank you!
