DOA kernel-4.15.0-0.rc8.git2.1.fc28.x86_64

[Chris Murphy]

Two x86_64 UEFI computers (different CPUs and firmware OEMs) won't
boot this kernel.

On one computer, it reboots shortly after I see EFI stub: UEFI secure
boot enabled.
On another computer, I just get a hang with an underscore and it never recovers.

kernel-4.15.0-0.rc8.git1.1.fc28.x86_64 works fine on both.

Yeah, it seems very broken. I also get the immediate reboot experience.

Can you file a bugzilla for tracking?

Also does it work if you turn off Secure Boot?

Same behaviour here (reboot a few seconds after the system starts
booting the 2.1 kernel) on a system, that does not support secure boot
(Lenovo ThinkPad X220).

I noted this in the bugzilla but this should be fixed in the -rc9
release.

Thanks,
