Nayan, as a workaround you may add the pcie_port_pm=3Dforce op= tion 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?) d= ue to the risk of breakage since it is not just limited to amdgpu/radeon. Anot= her 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): https://msdn.microsoft.com/en-us/window= s/hardware/drivers/bringup/firmware-requirements-for-d3cold I'll bring this up with linux-pci developers after the weekend. Should I proceed with proposing workaround amdgpu/radeon patches?
