Can you retry with kernel-3.16.0-1.fc21 from
 http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=1975869 ?

--- Additional comment from Mark Hamzy on 2014-08-04 13:39:42 EDT ---

The same failure.

--- Additional comment from Dan Horák on 2014-08-15 06:42:15 EDT ---

Should be caused by a missing patch in our binutils
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=57fa7b8c7e59e35bced580f9bcb9668af43fdbce

kernel at http://fedora.danny.cz/ppc/kernel/ is rebuilt with the fixed binutils and works fine for me.

Comment 1 Dan Horák 2014-08-15 10:47:14 UTC

AFAICT RHEL binutils are also affected.
