Is it dependant on something else not merged yet ? I get rejects when I apply it to 2.6.15-git10 I don't have time to fix it up by hand right now (I was going to set a build going before I turned in for the night..) I'll poke at it again tomorrow. Another datapoint btw: I've another EM64T that works just fine. The one that fails is the only one that isn't using onboard VGA, this one has a PCIE Radeon. Given it happens when X is starting up, it could be that the X radeon driver does something special which is why others aren't seeing this. Dave
