Hi,
I've got a Pinephone that I can't set up (https://github.com/ubports/ubuntu-touch/issues/1488) but the serial console appears to be usable (except for panic messages every 30 seconds or so). Surprisingly, it made some kind of notification beep while frozen so my questions are as follows:

• What's the username and password to log in on the serial console?

• Can I retrieve whatever message came in, and if so, how?
