Upstream 4.4.110 commit 20cbe9a3aa2e was back ported to Xenial as commit f8365429a3dc1. However, the backport failed to remove a kfree(), which the original patch did:

@@ -381,7 +415,6 @@ static void release_ds_buffer(int cpu)
                return;

        per_cpu(cpu_hw_events, cpu).ds = NULL;
- kfree(ds);
 }

I'm building a Xenial test kernel now with the kfree removed. I will post it shortly.
