The following did the trick:

diff --git a/kernel/audit.c b/kernel/audit.c
--- a/kernel/audit.c
+++ b/kernel/audit.c
@@ -291,8 +291,10 @@ int kauditd_thread(void *dummy)

                       add_wait_queue(&kauditd_wait, &wait);

-                       if (!skb_queue_len(&audit_skb_queue))
+                       if (!skb_queue_len(&audit_skb_queue)) {

                               schedule();
