System fails to properly boot after update

After a pacman -Syu and reboot the system stops further booting with what's visible on the photo. No logs files are produced. The keyboard doesn't work, however if any devices are plugged into USB, more messages do show up about those devices and their connection status. This is the first time something like that happened. What do I do now? Do I reinstall the whole thing?

You can see there is the end of an error message there, but not the start which would probably say more about it. One way to get this info is video the boot as it's possible to stop the video at various points then. Something to try, that may or may not help shed more light on the error and exactly when it occurs in the boot that someone could then make further suggestions. Quite easy if you have something to take digital videos, less so otherwise of course  ;D

You can chroot into installation partition using live bootable artix linux usb and mount boot partition if needed , then reinstall kernel

The video option may not be possible, I think when the screen pops up, it's already in this state - which means the messages are pushed to the screen faster than the display hardware is able to light up.

I did a chroot and installed a LTS kernel, but then during boot it was stopping with a message about missing modules. I think it was possible to have multiple kernels installed, or am I wrong?

Yes you can have multiple kernels
Edit: which modules are missing?

First of all, always stay calm!

Even if the update runs without errors, such images appear sporadically after a kernel update.
The system stops because there are probably still remnants of old firmware or drivers in the memory and therefore the hardware is not yet ready for a restart.

I can only recommend: after a kernel update, shut down the system, switch it off and only then start it up.

Which parts of "probably" and "sporadically" did you not understand?

I'm no stranger to such images, but I haven't seen them often enough, so I don't waste time troubleshooting, especially since the affected systems (which I maintain) work fine for months after a cold start.
Apart from that, the revered thread creator (as well as quite a few other questioners) doesn't provide any useful information and I don't think to ask for it.

Consequently, if you know of better explanations and better solutions, bring them on.

I had this problem yesterday on an AMD cpu.

I set kernel command line parameter spectre_v2=off.

The next kernel release should solve this.

If your system is faster than your display can turn on I guess that won't work then, although it could scroll by really quickly so you don't see it. In that case there are some logging options if you look at the mkinitcpio man page, such as putting rd.debug and rd.log on the kernel command line, possibly rd.break could be helpful too. I found some boot failure error like that once although that was using dracut. Of course, if Maghera's solution works then the problem is solved without need to investigate the cause any further!  8)

The new kernel 5.18.16-artix1-1 has been released and Artix is booting ok again.(for me anyway).

@Maghera, thanks for the info, apparently many people were bit by this issue. @#######, thanks for useful tips, I wish I don't have to use them though ; ) problem solved.
