Hi Jonathan, thank you for your answer.

I gave a try to linux-image-3.7-trunk-amd64

The system is sluggish and unresponsive when logged under gnome.
For example, using "vblank_mode=0 glxgears" lead to a score of 2 orders 
of magnitude less than with 2.6 kernel (10 instead of 1000 for the same 
windows size).

But, there is no message in dmesg this time.

Should I report this to intellinuxgraphics.org even with no error messages ?
