Weird bug upon login

Hi there, I experienced a weird bug today. The situation was:

1. I logged in as normal. I ran checkupdates, then sudo pacman -Syu to update. Sudo didn't accept my password (It always did accept it so far).

2. I logged out to see whether I can log back in or not. I couldn't. About 4-5 times at least. I checked carefully whether my password was correct. I use that many times a day so I can't just forget it.

3. I tried logging in as root but I couldn't (honestly, I'm not at all sure if I typed the actual root password or an older version. My fault. Don't take this point 3 seriously because of this).

4. I rebooted the computer to see what's going on.

5. I tried logging in again. When I wasn't sure I typed the correct password, I hit backspace several times. I got a wall of text with some kernel messages that I didn't understand.
This is where I began to think that it was a bug. It shouldn't throw a wall of text when I hit backspace in the login password prompt. I'm not 100% sure that this wall of text appeared after the reboot, but I think it did.

6. I could log in somehow. I updated the system and installed linux-lts with the headers in order to have a backup kernel.

7. Because I think this is a bug, I changed both my user's and root's passwords, just to be sure.

Additional info: I intentionally use the default, cli login. I don't autostart X server after logging in, I do that manually. So when I tried pacman -Syu, I still used the cli.

sudo journalctl | grep 'aug 21' output

What do you think, what was this?

Edit:
The kernel was:
Linux Lemongrass-pc 4.12.8-2-ARCH #1 SMP PREEMPT Fri Aug 18 14:08:02 UTC 2017 x86_64 GNU/Linux

Edit 2:
I use zsh as default shell.

Thank you for your reply!
Here you go:

All of today's entries are noted after I logged in and updated the system.

Edit: I do full updates. No package is ignored.

Edit 2: Since the initial post, the issue hasn't come back.
