If someone want to use DAGFIX version http://download.simplemining.net/simpleminer-RX-v1118_dagfix_computekernel.img.zip Still yes there are problems with too many GPUs. And there is nothing i can do about it. We still need to wait for AMD to release normal linux driver with this fix so i could install it to normal version of image. For now this is only solution for linux.
