Full quote follows. Can we get a full dmesg, to know if thing like IOMMU are enabled or not. This is even more puzzling as rv710 has 40bit dma mask iirc and thus you should be fine even without IOMMU. But given the patch you point to, it really can only be something that allocate page in place the GPU fails to access. Thomas how much memory do you have (again dmes will also provide mapping informations) ? My guess is that the pcie bridge can only remap dma page with 32bit dma mask while the gpu is fine with 40bit dma mask. I always thought that the pcie/pci code did take care of such thing for us.
