Comment 4 for bug 542251

Ok. That's odd. The problem here appears to be here:
[ 5.228897] Linux agpgart interface v0.103

It looks like a race between the drm driver and agp setups; drm has bailed because it's tried to access the agpgart, but that module seems to be currently initialising.

I'm moving this to the kernel, where the drm modules belong. How often can you reproduce this? Does it happen only on the first boot from power-off, or seemingly at random?
