The nva3 copy engine exhibits random memory corruption in at least one case, the GeForce 320M (nv50, 0xaf) in the MacBookAir3,1. This patch omits creating the engine for the specific chipset, falling back to M2MF, which kills the symptoms. Signed-off-by: Henrik Rydberg <rydberg at euromail.se> --- Hi Ben, this patch is still needed in 3.6-rc1, so perhaps we should apply it after all. I have been running it without problems for a long time now. Thanks, Henrik drivers/gpu/drm/nouveau/nouveau_state.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drive...

Hi Ben, Dave, Since 3.5-rc0, I have been experiencing occasional screen corruption on my MacBookAir3,1, using a GeForce 320M (nv50, 0xaf). The X driver version is xf86-video-nouvea-1.0.1-1 (arch). I do not know what the root problem is, but I have been able to isolate the symptoms to the usage of nva3_copy.c. The patch below is the least intrusive way I could find which kills the symptoms.

Hi Ben, The new mutexes in nvc0/nv50 (fadb17190/b509656) break resume on my MBA3,1. A dead-lock somewhere, perhaps? Reverting fixes the problem. Thanks, Henrik
