Actually, I have taken same patches of yours which proposed and applied it correctly. Will try it with clean
build if that helps.

But what I could understand from following patch is https://patchwork.codeaurora.org/patch/207653/ 

We still have a flow of pci_aspm_init() -> alloc_pcie_link_state() -> pci_function_0()
Where I see the first Kernel NULL pointer crash while accessing pdev->subordinate in pci_function_0() function.

OK. It looks like somebody moved function_0 call around. I was looking at 4.11-rc1.

3bd7db63a841e8c5297bb18ad801df67d5e38ad2 (PCI/ASPM: Always set link->downstream to avoid NULL dereference on remove)

I see the change in 4.11-rc3 now. 

Let me see what's going on.

I posted V6 a minute ago with the bugfix. Let me know how that works for you.
