is this when you start X by chance ?
and is this a radeon videochipset ?

Yes, right before agpgart is loaded and gdm is started.

Comment 3 David 2004-04-12 14:49:16 EDT
It seems that the 319 kernel fixes the messages. So far I did have
some kernel panics with the 315 kernel, also seemingly X-related (e.g.
when I closed down X). No such problems so far with the 319 kernel.
keep up the good work.
