So a bit more testing. I was using a bit of "unusual" config I guess, having 2 GPUs and some other pcie cards (10G, ..). So I simplified and went to the most standard thing I could think of, _just_ the RX 560 card plugged into the main PCIe 16x slot directly connected to the CPU. And exact same results, no change in behavior. So on one hand I'm happy that the other cards and having the AMD GPU in the second slot isn't the issue (because I really need that config that way), but on the other, I'm no closer to finding the issue :/ Cheers, Sylvain Munaut _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
