Title:
  Boot fails with Linux 6.14 on MacBook Pro

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed

Bug description:
  I upgraded to Plucky today and was greeted by a black screen after
  restarting. Since I can still get into GRUB, I tried booting with the
  old kernel (6.11) and that works fine.

  When selecting 6.14 the entire machine appears to lock up. I get no
  output whatsoever, so the screen is either entirely black or has two
  lines of text¹.

  My machine is a MacBook Pro 2012. There should be more hardware
  details attached.

  ¹) I fail to recall the exact content. I think "Loading image..." or
  something like that.
