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.
