full kernel message log up and including the oops

Hi,

my notebook has a
01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10].
When I try booting with video=radeon:modeset=1, the system oopses and freezes with
[   12.501727] Linux agpgart interface v0.103
[   12.574951] [drm] Initialized drm 1.1.0 20060810

Problem is that the agpgart module isn't loaded before drm.
Comment 2 Marc Haber 2010-04-09 17:59:48 UTC
Really? The log doesn't contain the string "drm" before "Linux agpgart interface v0.103"?

Greetings

This doesn't happen on my system any more with 2.6.34 (probably even with an earlier version).
