In the future, it would be helpful if you replied to the PR saying so. It
looks like it was closed at your request as you stated the problem had gone
away, so I've been working under the assumption that the problem has gone
away, as that's the last information I have.

I have appealed a number of times on the freebsd-security mailing list and
eslewhere for information from people who could reproduce the problem. In
general the replies I got were that people either had the problem go away with
recent 6.x, or that they did not have time or were not interested in helping
debug the problem. If you are interested, please take a look at my recent
reply to the reported problem, and work through the steps there. I strongly
recommend using a serial console on the box. I can only debug a problem if I
know it exists, and with enough information, and so far, there's been
insufficient information to track down the problem.
