Hi,
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).

Getting logs is tricky because the system appears to freeze at that point.
Is this a known issue? Anything we can do to help diagnosis?
I'm not aware of any specific issues. Please file a bug and attach your logs (https://bugs.freedesktop.org) along with information about the system.
