    Polaris driver bug



      I am having trouble with my video compression application

      I am encoding either 2K (2048x1080) or 4K (4096x2160 RGB images. Encoding 2K runs fine, while 4K causes a crash

      after 10 minutes or so.  This is a hard crash - once I exit the program, the computer stops working and I need to reboot.


      I did an experiment and I disabled all of my kernels ( i.e. put a return as first statement), and application still crashes.

      So, it looks like there is a problem either copying data from host to device, or from device to host, because with my experiment,

      there is no compute going on.


      Environment is:


      Fresh windows 10 install

      Latest Crimson driver

      two 4 GB RX 470 cards (only running on one of them)


      Any ideas on how to troubleshoot this would be greatly appreciated.
