Do you have a reference for the G1000 running Linux? Thanks.

I don't think it does or it would be listed here: https://developer.garmin.com/open-source/linux/

I've seen a kernel panic on G1000 once, does not feel like a Linux (unless they also heavily modified the panic handler)

Ooo, what did it look like? A Mach kernel oops (aka "just start painting text from the top-left"), a BSOD (more structured), a dialog box over the top, or...?

Also what info was printed? An inscrutable Guru Meditation, a register dump, or...?

Just idly fascinated to figure out how much info would be dumped by a piece of avionics running in end-user production mode.

lol yeah, I was very sad that I forgot to take a pic but it's black and white, text on top-left and it's just a register dump.

I went on a bit of a rabbithole trying to look for firmware downloads for the G1000 to run `strings` on but sadly they're not publicly available anywhere.

But I'm very happy to be able to say that you don't need to be sad you didn't get a photo anymore because I found https://mooneyspace.com/topic/21333-g1000-pfd-start-up-error... :D

No amount of quote-googling got me any further though, which was why I went firmware hunting. Now at least I have a good conversation starter for anyone who looks like they might have a dealer account next time I'm at a hangar though...
