RC1 events/0 CPU usage

Hi, I have a shiny new Intel Core Duo T2300 laptop with an nvidia geforce go 7400 graphics chipset. When I boot into Linux, there is a process in 'top' that is showing a 90% average cpu usage and it won't stop. I cannot kill it. There is an events/1 process that is always at 0%. I assume this is something to do with the processor and perhaps acpi, since there are two events processes and my processor has two cores. Any suggestions on what the problem may be? I have tried: 1. running with the basic provided graphics drivers for nvidia and no change 2. running with the nvidia provided graphics drivers and no change other than improved video performance Jon.
