An update on the ”Unknown symbol swiotlb_map_sg_attrs” issue with Kernel 4.16-rc and the latest NVIDIA drivers (384.111 and 390.25)..
From more testing done after I posted brief details on the NVIDIA Forum, it would appear that – as is sometimes the case – this one issue may have been masking further problems.. See https://devtalk.nvidia.com/default/topic/1030082/linux/kernel-4-16-rc1-breaks-latest-drivers-unknown-symbol-swiotlb_map_sg_attrs-/ for more info..
This may account for the lack of any updates from NVIDIA – so far.. Thanks are due to mm0hgw and towo for their work on testing this..
