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.
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.
