(while i'm on a roll ...)
on this gateway m-1626, shortly after f11 beta starts to run, the cooling fan kicks into this regular oscillation with a period of about 4 seconds -- speed up, slow down, speed up, slow down ... you get the idea.
to test that it's not a HW issue, i rebooted and hopped into the BIOS and let it sit there for several minutes, whereupon it ran nice and smoothly the entire time.
as soon as i rebooted fedora and got to my GNOME desktop, the oscillation started up again. occasionally, it will calm down briefly but that doesn't last long.
anyone else seeing this?

I'd say, file a bug.
Try playing with the GOVERNOR, MIN_SPEED and MAX_SPEED variables in /etc/sysconfig/cpuspeed as well, and include the results in your bug report.
Cheers

against which component? the kernel?

Yes.
I still think playing with cpuspeed (for instance, keeping the frequency at the lowest level possible, or highest) will let you know if it's a thermal oscillation issue, or a fan control issue.

Just to check the obvious, does your CPU usage exhibit a similar pattern? If CPU usage is relatively constant, it sounds like an overcompensation bug of some kind.
-B.

You said earlier this Gateway unit is refurbished? I wonder if it is a physical fan or a power supply problem. I'm pretty accustomed to EMachines and Gateway units coming with the cheapest possible power supplies. Which go bad, it seems. I tend to plug even my laptop power brick into a good UPS unit rather than the wall outlet itself, because in my area, power spikes and sags are pretty routine.
