Hello,
Did you start to bisect from v3.18-rc1?
I'd like to be sure that this is another bug which is fixed by following commit.
commit 85c9f4b04a08f6bc770b77530c22d04103468b8f
Author: Joonsoo Kim <iamjoonsoo.kim@xxxxxxx>
Date: Mon Oct 13 15:51:01 2014 -0700
mm/slab: fix unaligned access on sparc64
This fix is merged into v3.18-rc1 sometime later that
'support slab merge' is merged.
Thanks.
