Hello, I somehow had managed to mess up my build system and only yesterday got it back to compiling properly.

This is on a Lenovo A485 Laptop, which is an AMD Ryzen processor and a Radeon Vega graphics. My last known working revision is r352987. Here are bits of the core dump, I hope they are useful, if more information is needed, please don't hesitate to ask. BTW: I usually compile GENERIC-NODEBUG, if that results in the dump being useless (sadly I can't tell), I can disable all the performance goodies and compile GENERIC :-). -- Evilham Fatal trap 12:
