It worked for me for a while, and most part while I wasn't properly running 3D rendering, but OpenCL codes instead. But it never worked as a workaround cause it just randomized the time to happen the errors. And this is exactly why I didn't mention it before. Indeed, I need to test it on kernel 4.18 yet. ############################################################################### In time : seems like that the warranty of my motherboard will take a long time to finish. I borrowed an old PC from my aunt and I hope that it will be enough to compile the kernel and test the GPU. It is going to be fun to compile a kernel on a 1.6GHz dual core (1C/2T).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
