I provisionally reverted 68db9bc81436 ("PCI: pciehp: Add runtime PM
support for PCIe hotplug ports") on my for-linus branch while this is
being debugged.

To be clear, this revert is only a last resort to avoid releasing
v4.10 with a regression. I hope and assume we'll have a real fix
before v4.10 and we'll be able to drop the revert in favor of the fix.

Can someone please open a kernel.org bugzilla, mark it as a
regression, and attach the complete dmesg log and "lspci -vv" output?
Please mention that bugzilla in the changelog of the fix.
