This is a fresh installation of Manjaro, installed using Manjaro Architect on an existing LVM partition inside a LUKS-encrypted partition and using a separate unencrypted boot partition. I've reinstalled several times, with the same result every time.

The problem manifests itself on the second and subsequent boots, in which systemd-modules-load.service will fail, although the boot will continue for a bit before it hangs without any further error messages.

Fortunately after a while I can switch to another tty to examine the issue, and what I've discovered so far is this:

  • The boot hangs because Xorg fails to load because the nvidia driver fails to load because the nvidia kernel module has not been loaded.
  • systemd-modules-load.service seems to fail because /usr/lib/modules does not exist. It succeeds on first boot, but then after the first boot the directory is gone and subsequent boots will fail.

I can recover by reinstalling the kernel (linux417) and nvidia driver (linux417-nvidia) which will work for exactly one boot before /usr/lib/modules disappears again.

So my questions are:

  • What could possibly be causing this during the boot process?
  • How can I proceed to find more clues?

Manjaro includes a kernel-alive package which provides a systemd service called linux-module-cleanup that is supposed to clean up old kernel modules, but apparently has a bug in it that causes it to just wipe the entire /usr/lib/modules directory...

The solution is to just disable the service with systemctl disable linux-module-cleanup.service, or you could probably also just remove the kernel-alive package.

Credit goes to jonathon on the Manjaro forums for suggesting this.
