This happens every time when xmr-stak 2.10.5 (w. ROCm 2.5) tries to compile shaders for this R9 290X. An ~/.AMD archive is generated but the compilation process never finishes. When I close the shell with xmr-stak running (CTRL-C xmr-stack does not work), I get this kernel BUG. I used a 5.2-rc6 debug kernel, but it happens on 5.1.15 too.
