<pre>Nayan, as a workaround you may add the pcie_port_pm=force option to your kernel
command line, then you should not need the patch. Can you check this?
Alex, I don't think that the minimum date should change in 4.8 (and 4.9?) due
to the risk of breakage since it is not just limited to amdgpu/radeon. Another
concern is that while the year seems a good heuristic, it does not match the
checks that Windows 8 performs (which may or may not be an issue):

I'll bring this up with linux-pci developers after the weekend. Should I
proceed with proposing workaround amdgpu/radeon patches?</pre>
