 Decoding h264 stream using h264_cuvid causes a NVRM XID 31 (NVidia driver
 http://docs.nvidia.com/deploy/xid-errors/index.html indicates XID 31 is a
 "GPU memory page fault", and can be either the Driver or the Application's

 Replicating is as simple as:
 ffmpeg -c:v h264_cuvid -i ./bbb_sunflower_1080p_30fps_stereo_abl.mp4

 After the error, ffmpeg hangs (waiting on IO), and seemingly anything else
 querying the NVidia driver also hangs (e.g. nvidia-smi run at the same
 time will hang).  Killing ffmpeg (goes zombie still waiting on IO), and
 waiting a few minutes eventually unfreezes and allows normal use of the
 NVidia drivers again.

 Not sure if this is ffmpeg or the NVidia drivers, but I figured I'd post
 here first ;).

 I originally encountered this on a system with a Tesla P40 and a 1080TI,
 and have also replicated it on another system with only a 1080TI (same
 software stack on both).

 This is using:
 ffmpeg 3.3.5
 linux 4.4.87-gentoo-r2-rev1.16
 nvidia-drivers 384.90
 nvidia-cuda-cudnn 9.0-r1
 nvidia-cuda-sdk 9.0.176
 nvidia-cuda-toolkit 9.0.176
 nvidia-video-sdk 6.0.1
