(sorry it replys automaticaly only to the sender - now added the list)

What do the intel-gfx people think?

====== original mail follows =======
Hi sorry for bothering you once again.

I noticed most of the issues are coming from drm (I have the stupid "Intel
Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics
Controller (rev 03)")

So I checked today the logs again and found out it crashed in the mornign when
turning on the notebook in the office.

Is there something you can conclude from the trace below and another
question - why is it checking CRTC as I have LVDS, VGA1 and DVI1 - actually
using only the LVDS and DVI outputs

Thanks again for taking your time
