NAK, this patch is not needed currently 1, Because TDR feature is still undergoing, so all patches related with TDR should pending now 2, I don't think this is needed, @Pixel can you get the latest amd-staging-4.9 driver and try it, see if the "vm fault" duplicated without this patch? Because I remember no such issue In staging driver
