This kind of tracing is mostly useful if the person with the problem intends to do the debugging, so you can tell what point things happen, make changes and try something else. Imagine running strace on your browser and asking someone to tell you why a web page doesn't render properly from the logs, that's about the same degree of complexity.</div><div><br></div><div>Unfortunately you have a Tonga based GPU, which like Fiji, seems to have some sort of reset problem. We don't really know if the problem is with the hardware or something we're not accounting for when doing a bus reset.
