Version-Release number of selected component (if applicable):

kernel 0:3.20.0-0.rc0.git7.3.fc23

How reproducible:

Unknown.

Steps to Reproduce:
1. Boot the machine.
Comment 1 Richard W.M. Jones 2015-02-18 13:34:52 UTC 
Completely 100% reproducible with kernel-3.20.0-0.rc0.git7.3.fc23.aarch64.

Boots fine when I go back to kernel-3.19.0-0.rc7.git1.1.fc22.aarch64.

Comment 3 Kyle McMartin 2015-02-18 14:39:57 UTC 
probably more incompatibility between APM's upstream code and our firmware. sigh.
Comment 4 Kyle McMartin 2015-02-18 15:00:21 UTC 
http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=2886388

try this build when it finishes.

> sigh.

FWIW I'm using rh-0.13 because of incompatibility between rh-0.14
and our Fedora kernels.  I'm waiting eagerly for rh-0.15.

Will do.

It works!  Boots fine with 3.20.0-0.rc0.git7.3.bz1193875.fc23.aarch64
and I did some light host testing and it looks good.
Comment 8 Kyle McMartin 2015-02-18 22:24:38 UTC 
it'll be fixed in the next rawhide build (kernel-3.20.0-0.rc0.git9.1.fc23)
Comment 9 Kyle McMartin 2015-02-23 20:37:59 UTC 
fwiw, rh-0.15 is out internally, so please update to that.
Comment 10 Richard W.M. Jones 2015-02-24 11:05:05 UTC 
Firmware rh-0.15 + kernel-4.0.0-0.rc1.git0.1.fc23.aarch64
boots fine and NetworkManager works.
