Public bug reported:
Upgrading from Ubuntu 24.10 to 25.04 renders my MacBook Pro 2014
unusable, because it doesn't boot anymore. No error, the screen just
stays blank. Here's what I've tried:
- booting with systemd-boot EFI stub
- booting vmlinuz directly (using efibootmgr)
- enabling/disabling initrd
But the problem persists. The screen stays blank.
However, with the following methods booting a kernel works:
- going back to Ubuntu 24.10's kernel 6.11 works partly (kernel boots, but the
init process fails with an error)
- booting Ubuntu 25.04 Live from USB (kernel 6.14 works perfectly here)
** Affects: bcmwl (Ubuntu)
