Hi, I am experiencing a bug with nouveau with linux-3.7-rc3 (and since rc1), my video adapter is the one integrated on the MSI M3N78-VM motherboard (hence x86_64): 02:00.0 VGA compatible controller: NVIDIA Corporation C77 [GeForce 8200] (rev a2) (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.
