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.
“This just in - running commands that induce a kernel panic causes a kernel panic, we’ll have more at 11.”
The QR code is pretty dense , probably plenty of space to include the panic reason and stack trace.
Edit: For those of you that don’t know, exiting or crashing the init process (PID 1) causes the kernel to panic. Essentially it’s the, “Well what the hell do I do now if I have no processes to serve?” response.
Still, a QR code is a marked improvement on the “Something went wrong :(” message of recent Windows releases.
What’s with the snark? I’m just sharing what is funny (to me): that somebody gave a Linux kernel panic this aesthetic, referencing a familiar “feature” of a less loved OS.
On lemmy you’ll allways find the weirdos and elitists that have been pushed out of the mainstream.
The linux equivalent of bsod has been introduced pretty recently, so it’s normal for few people to have experienced it yet.
Also somewhat relevant xkcd: https://xkcd.com/1053/
I get what you mean but this is not fediverse-specific.
I have meanwhile found out that the screen above was not produced by systemd but rather by the drm_panic kernel module. Makes sense since systemd wasn’t running when it happened.
Next time it happens (hopefully not) I’ll try to switch ttys, maybe the logs are still visible, white on black.
It’s a subculture phenomenon, and lemmy linux is a subculture of a subculture, so it’s more intense.
I’ve been a moderator on some linux reddits in the past. And the less users there were in the sub, the more negativity, rudeness, gatekeeping and other toxicity was there. But ofc what I say is just an opinion based on my subjective experience so idk.
The linux kernel bsod is even younger than that, august 2024 iirc.
