Robin, you do indeed have a painfully slow boot, but the audit_skb_entries in your logs are, like the others here, just the last thing the kernel happened to log. The AppArmor processes in your boot take ~1.6 seconds (if I've estimated them correctly), most of which appears to be spent asleep waiting on IO. Even if we could cut the AppArmor time in half (we can't, btw) it wouldn't even come close to denting your boot up time -- while those tasks are running your system is busy doing disk IO.
