Hi!
I wanted to test Fedora Rawhide so I ran `dnf system-upgrade download
--releasever rawhide --exclude=sdubby` (as per
https://bugzilla.redhat.com/show_bug.cgi?id=2243872#c12) to upgrade from
Fedora 39 and it finished successfully. However after I ran `dnf
system-upgrade reboot` and got a black screen after the system upgrade
progress bar. And I can no longer boot into the Fedora partition and only
get a black screen. Before that, I was able to use Fedora 39 alongside
macOS just fine.
Has anyone been able to run Rawhide on an x86 MacBook Pro (2016) or a
similar x86 Mac* device? And what can I do to further investigate the boot
issue?
Can you display the GRUB menu (listing all the installed kernels), when you
repeatedly press F8 after starting the laptop? (A question is whether Mac
keyboard actually sends F8 by default, perhaps connect an external one). If
you can see GRUB, try older kernels. On the latest kernel, you can edit the
command line and remove "rhgb quit" to see some boot debug messages.
Note: I noticed that after the upgrade, the name in the mac boot menu
changed from “Fedora” to “UEFI Boot” and the symbol is still the Fedora
logo, not sure what this means. So could it be the efibootmgr-related bug
that was recently fixed in the Fedora 39 nightly ISO (
https://bugzilla.redhat.com/show_bug.cgi?id=2239316)?
Note 2: I also couldn't go past the initial menu when I used the Fedora
Rawhide ISO a few days ago (around Oct 10 iirc), not sure if this is
related.
If you decide to reinstall F39 on that laptop, I'd recommend just
continuing testing with Rawhide ISOs, so that you don't break your system
again needlessly. The ISO needs to boot, that's a prerequisite. If it
doesn't, please file a bug and link it here, we'll make it a blocker bug
for Fedora 40.
Thanks for testing.
