These greetings are independent of Mesa (versions 9.2.5 - 10.3.2), xf86-video-intel (any up to and including 2.99.916), libdrm up to and including v2.4.58, as well as other boards utilizing the i915 driver. I use the Gallium driver as I need OpenGL V2 support - I can't begin to express my gratefulness for the Gallium driver. I have not tested with an OpenGL v1.4 driver yet. Enclosed is the kernel .config file common to all kernels using Intel embedded graphics. This kernel (3.18 rc3) also introduces performance issues after the warning and eventually hangs with no message or trace. rc1 continues to run and does not hang. Sorry, I'm unable to give more info as I am on the road - I continue to receive my mail though. I donate my time in the Philippines teaching all ages computer science and as such I can only afford used hardware, or computers that are donated, in my classes. My newest machine (except my personal) is a core 2 processor. (LGA775 socketed motherboards.)
