I can’t seem to get any kernel of 5.7 (5.6 or lower is fine) or higher to boot on my MacBook Pro. It doesn’t even get to the login screen. The screen just stays black on boot.
It’s a 2015, i7, with onboard graphics (using i915 driver) and I suspect the graphics are the issue here but I don’t really know how to investigate this.
How can I get a log or some other indication of what is causing the problem?
