CPU underload

[Adrian Chadd]

OK, so those messages are expected when you run hwpmc. Sigh, I should
just rate limit that message and make it a counter. (I had to comment
it out here.)

Do you get those unaligned fixup messages when you're not running
hwpmc? (sysctl kern.msgbuf_clear=1 and then retest without running
pmcstat, etc.)

During the test, what's the latency between your two test boxes? Try a
ping from FTP client->server and see.

Thanks,
