[SOLVED] Arch doesn't boot after update

I'm pretty bad at remembering to update so it only happens once in a blue moon.

After running pacman -Syu and rebooting, it got stuck. The place at which this happens isn't always the same.

I couldn't switch TTYs, so I used a live USB to try and see what was wrong.

Here is the output of journalctl -b -1 -r:

Re: [SOLVED] Arch doesn't boot after update

The log shows the system booting up and shutting down.  If the journal is for the boot with the issue,  what was on the screen during the system being stuck?

It showed the systemd messages, all preceeded by either [ OK ] or nothing at all. The place in which it hangs is different each time.

The log shows the system booting up and shutting down because I pressed the power button in order to boot into the live USB and get the log. You can see where this happens if you search for "pressed" in the log.

Re: [SOLVED] Arch doesn't boot after update

Have you tried disabling /etc/udev/rules.d/90-xhc_sleep.rules ?

No, I haven't. Should I try removing the rule concerning ATTR{power/wakeup}? All the errors in journal seem to be related to that.

That rule or the whole file which ever you want to test.

Re: [SOLVED] Arch doesn't boot after update

That actually happened to be the only rule in the file. Unfortunately, removing it did not fix the problem. Here are the new logs:

Re: [SOLVED] Arch doesn't boot after update

Is a GUI supposed to start or is it the login prompt that is missing?

I can see some issues in the journal but not sure they if are related:

Jun 15 17:09:24 daniel systemd[1]: mbpfan.service: Failed with result 'exit-code'.
..
Jun 15 17:09:23 daniel systemd-modules-load[310]: Failed to find module 'facetimehd'

In terms of a GUI, I always start X manually.

It hangs before the login prompt appears--systemd gets stuck, but in a different place each time.

"FaceTimeHD" has to do with the Webcam, but that worked out of the box iirc. However, the mbpfan thing is weird because my fan does start running after my laptop gets warm. Should I try disabling that?

Re: [SOLVED] Arch doesn't boot after update

I would try it.  Another thing to try would be linux-lts.  What was in the update?  (/var/log/pacman.log)

I do a poor job of maintaining my install so each time I update, basically every package gets updated

Disabling mbpfan did not work; I will try linux-lts

Re: [SOLVED] Arch doesn't boot after update

There are a few bugs with drm/i915 with 5.7.2. Based on your hardware, I would say that is causing your system to not boot. I am waiting for these fixes too.

I have same hardware and for me, MBP fan and facetimehd are just distractions.  MBP complains about coretemp support so wont start (but never broke regular boot). For me I always need to load facetimehd manually.

For now, using any kernel from prior series 5.6 or prior (eg. lts or hardened) should allow you to boot into system (as does mine).

Re: [SOLVED] Arch doesn't boot after update

Thank you so much for the info. Changing to LTS totally worked. I'm honestly so glad I am not the only one with this setup.

For future reference, will compatibility be made clear in future releases or should I just keep trying them until they work?
