final edit: You want real logs instead? add this to your kernel command: drm.panic_screen=kmsg
Kinda funny, kinda neat.
I have no idea what the QR-code might reveal (I could not read it from this picture), so I pixelised it just to be sure.
FWIW I know exactly what happened and did not panic. To reproduce, boot your device with init=/bin/sh, then type exit.
CachyOS
The picture above is generated by Drm panic which is part of the kernel itself, or maybe a separate module. The data in the QR code is the kmsg log.
Not systemd, which wasn’t running when that happened.
And it’s been around for years; I guess I haven’t had a kernel panic in a long time.
Hey, I happened to have a handful of smartphones that still have an ok battery and just collect dust in the shelf.
If you want me to ship one to you, pm your address.
Gonna help my linux buddies so that they can scan QR codes if their OS crashes.
