Okay, I'm having a problem with 2.6.24-rc4 that I didn't with 2.6.23-rc6.

When the problem hits, my mouse (synaptics touchpad) is randomly
moving about and clicking things whenever I have my finger on the
trackpad. This behavior will persists for five to ten minutes (is
happening now), and seems to be triggered by load (watching online
videos in flash player, for example -- this matches Mark's experience
with a make -j4).

I *think* the touchpad is connected via ps2, which looks like it'd
clear usb of any blame. It's /dev/input/event6 at any rate.

This has been happening about once a day, and seems to start because
of high CPU usage. ONce the CPU is idle, it still happens though, so
I'm not sure why it clears up.

Any clues for where I should hunt from here?
