Created attachment 131886 [details] Trace/freeze on amdgpu modprobing As reported by Daniel Drake in [0] We are working with new laptops that have the AMD Bristol Ridge chipset with this SoC: AMD A10-9620P RADEON R5, 10 COMPUTE CORES 4C+6G I think this is the Bristol Ridge chipset. During boot, the display becomes unusable at the point where the amdgpu driver loads. You can see at least two horizontal lines of garbage at this point. We have reproduced on 4.8, 4.10 and linus master (early 4.12). Photo: http://pasteboard.co/qrC9mh4p.jpg In attachment the log taken using netconsole on amdgpu modprobing.
