However, a new update for "linux-ubuntu-modules-2.6.24-generic" just showed up in Update Manager this morning, maybe that will fix it. The updates (56 of them! Yeah, things change quickly in beta. ) are currently being downloaded.
Ububtu 8.10 had the same problem: my laptop (a T7100 dual core @ 1.8 GHz) run at 800 MHz - Now it regained its full power, thank you all!

Default disable all CPU eaters

Not sure if it relates to ubuntu, but...

in openSUSE, I surely disabled the screensaver and ran a 4-cpu job.
Later, the OS posed me with a game of hide-and-seek: every time I'd leave "top" running in a shell and later come back after a while and wake up the display - top shows the load of 5.0 but only 4 processes are running. what the hell!?

So, I opened a firewall hole for ssh and started peeking at the computer from a remote ssh - and lo and behold: as soon as 10 minutes of inactivity passes, the screensaver doesn't start (it is disabled), beagled starts indexing the home directory... the silly dog. Steals additional 1.0 load, indexing the growing sieve results files... Disabled it. Now 24x7 the load is strictly 4.0, and no nonsense is running and stealing the cycles. --the end

Ah yes, beagled. It's been a particular nuisance for us at work, the load on the main NFS server when eight virtual machines all start their beagles is quite troublesome.

I haven't had the problem at home since I keep the sieve files in /home/nfsworld rather than in my own home directory.
