I've noticed some strange fan behavior on my laptop after upgrading to Fedora
11. Sometimes right after Fedora loads and I log in the fan is running where it
is audible, but the temperature sensors show it's cold. After a couple minutes
it settles down to normal where I only hear the fan if things get warm from
heavy CPU or wireless use. I've also noticed that sometimes the Gnome battery
indicator stays full when I'm running on battery. So there are more than a
couple hardware glitches.

hm, I think I've actually noticed the same thing as jason on my hp pavillion laptop-- both with the fan (being loud) and the battery indicator since upgrading to F11
