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