Sometimes all text-mode terminals on my machine become blank (just a cursor in the top left corner, like on tty8+ by default) after a while and I can't reproduce it reliably.
What logs can I check or how should I filter journalctl to see everything related to TTYs?
I tried to use strace on agetty processes and they don't do anything at all.

The login prompt is there but it's not shown. I can login and execute commands, but the screen stays blank (or with messages left from boot). agetty --reload changes nothing.

I had the same problem on Arch some time ago. The problem was the 4.4 kernel. After upgrading to >=4.5 the problem was gone.
