--- Comment #8 from Maxim Cournoyer maxim.cournoyer@gmail.com --- I managed to make it work by compiling latest 4.13.0-rc2+ from there: git://people.freedesktop.org/~agd5f/linux. I used the 'drm-next-4.14-wip' branch, and customized it a bit (added CIK option for amdgpu driver, removed AGP support, bumped event rate to 1000 Hz, dropped a few Intel specific options (I'm using AMD K10 class CPU) and enabled a few AMD specific options. I'll try to narrow down exactly what fixes it, but one thing we can see is that there is no longer clock source skew problems apparent in the kernel messages.
