It compiled fine but crashed on boot. I've no way to copy the screen. I can send along a digital photo if the following isn't enough info. QUESTION: Should I be able to run ati-drivers-8.28.8 with this kernel or would I have to wait for ATI to put out a 2.6.18 compatible driver? The current version does not emerge with 2.6.18-rt2.

Been awhile since I've sent along crash reports. I'll have to ge a second Linux machine running to do the console boot capture thing if you need it.
