Bug Description
Since upgrading from Lucid to Maverick RC, X appears to stutter every 10 seconds. Mouse/Keyboard input freezes momentarily. Video playback stutters every 10 seconds or so making it hard to watch. I had no such problems with Lucid.
Dell Latitude D505
Running Gnome. Visual Effects are off.
Graphics: Intel 82852/855GM Integrated
I looked at http://
I tried adding the boot parameters intel_idle.

I've looked in top, and the freezes seem to coincide with a kslowd000 process appearing at the top, using 17.5% CPU.
I don't know what kslowd is, or if this is just co-incidence. Is there is a way to disable this process to prove whether it is the cause?
