Iʼve encountered a following kernel panic; dump in the console:

Snapshot of the display:

Not sure what I did exactly but roughly: opened a README.md (waited to open completely), clicked on a link there and closed the text editor (could be also other way around?); then, I think, the page did not even end loading before panic happened.

Hopefully, the above is helpful in any way…! 😯
