Comment 1 Itaru Kitayama 2015-12-29 04:54:44 UTC 
I am using the EFI v2.40. Is this version something expected to work with
the f24 or later kernels?
Comment 2 Andrew Jones 2016-01-04 14:35:51 UTC 
4.4.0-0.rc6.git1.1.fc24.aarch64 boots fine for me (with f23 userspace)
My firmware is a pretty old build though

4.4.0-0.rc6.git1.1.fc24.aarch64 doesn't boot on the Mustang I am using.

The firmware is a month older than yours (2015 March build).

Excerpt from dmesg just for the reference

With the below TianoCore and Slimpro, I was able to boot an f23 kernel, 4.3.3-300.fc23.aarch64.

Comment 6 Josh Boyer 2016-05-27 14:15:29 UTC 
Is this still an issue with 4.5.y?

No, 4.5.0-302.fc23.aarch64 boots fine with updated F/W.

Thank you.
