(Get the code!)
It's highly unlikely that the audit_printk_skb() function is itself slowing down your boot; it is designed to operate with extremely low overhead, and the ratelimiting that is in effect here means that the slowest portion of the function, actually writing characters to the system log, is skipped entirely.
Probably what is actually slow is recompiling AppArmor policies; this is an extremely computational heavy task that has been subject to extensive optimization. We're planning further caching efforts in the future to reduce the number of times that the policies must be recomputed. Chances are quite good a second reboot, immediately after this one, would run faster, since the profiles would probably not need to be rebuilt immediately.
Thanks
