Problem is that the agpgart module isn't loaded before drm. Really? The log doesn't contain the string "drm" before "Linux agpgart interface v0.103"? Greetings Marc This doesn't happen on my system any more with 2.6.34 (probably even with an earlier version). Greetings Marc Marking it as resolved |
