I'm using the gx1fb framebuffer for the geode. However, since this problem occurs even when the VT outputting the text is not active, I don't think it's fb related. The latency output is just a bunch of numbers. :P Here is some output with the latency -p 500 command, and halfway through it I put a 100% load on the cpu. == Sampling period: 500 us == Test mode: periodic user-mode task warming up...
