This smells a lot like a missing lock on an SMP or preemtable kernel. I'm not
thrilled about having to grab a lock before the first call to audit_log_start
and leaving it locked till the final audit_log_end for the event, since it
could easily be 4 or 5 start/end pairs to get all of it out.
Should be safe to rule out SMP. I'm running on a uni-processor, AMD64
(no hyperthreading) with an i686 kernel:
