Bug#992612: linux-image-5.10.0-8-amd64: Macbook3,1 fails to boot without nomodeset with nouveau



Hi Salvatore,
I used firmware-11.0.0-amd64-netinst.iso. And yes, I did not manually
install firmware-misc-nonfree since this initially failed, and I still
got a black screen which did not ever resolve or respond to VT
switching unless I used nomodeset and deleted quiet. (With quiet
removed, it doesn't black out, but it does stop ever responding after
it prints the "switching from EFI VGA" line.)

I'll reboot in a bit and wait longer and see what happens...

grep -C3 nouveau on syslog for, I believe, one of the failed boots says:
