Hi Peter,

I finally got around to building a test kernel for a user who had been
reporting this against F-14 (2.6.35) but they report there's not much
improvement.

Sorry. :/

Running this kernel is not any better. After leaving my system idle for
10 minutes I finally saw it dip below 0.10, but after leaving the
computer, and coming back 10 minutes later, I see a load of 0.25. No
programs running.

Before I hit "send" on this message, I ran uptime again and got this:
$ uptime
12:45:24 up 32 min, 3 users, load average: 0.82, 0.43, 0.34

Thunderbird was the only program running. 99.8% idle.
