It seems to hurt some hardware much worse than others. My BCM4306 Rev 2 could
not run without failure longer than ~6 hours, and sometimes as short as 10 minutes,
before the patch. I've now completed the equivalent of 3 weeks without a failure
(I'm running the preemptible periodic work every second instead of every minute).
