My machine is a UMBP 2.8GHz, 4gb RAM. I'm getting these kernel panics when I'm surfing online. They always happen when I'm using the trackpad to scroll. The really weird bit though is that it does not leave a panic report on the Console or in /Library/Logs. There was a report from last month in a "PanicReporter" folder but the log only lists the date "Tue Feb 17 23:22:59 2009". Maybe I'm looking in the wrong place?
