Yeah means the GMCH itself probably hung, possibly not responding to memory requests from the CPU. The display was otherwise idle when it froze? The behavior you describe sounds like a panic; there's a patch available to get some more info in that case: "vt/console: try harder to print output when panicing" that Dave Airlie just posted (attached). Can you apply it as well and see if you can reproduce the problem? Thanks, -- Jesse Barnes, Intel Open Source Technology Center
