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.

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.

    Those who would like to make extra sure their data stays private.

    Yes, well, exactly. You know not every question is a literal question, right?

    what kinds of data could be considered confidential in said log?

    I was wondering that myself. It’s “the kmsg log”, something to do with kernel mode switching or “graphics”. My guess: the log itself is not problematic, but there might be some metadata added. Or then one creates that metadata by submitting the QR code.
