Peter, I notice you weren't cc'ed on the last few messages of the
'PCI: Revert "PCI: Add runtime PM support for PCIe ports"' thread,
the similar bug https://bugzilla.kernel.org/show_bug.cgi?id=190861
turned out to be caused by locking issues in nouveau which were
fixed with 3846fd9b8600 in Linus' tree.  That commit swiftly got
reverted because it lacked prerequisites, and replaced by the
temporary fix cae9ff036eea + 15266ae38fe0.  These two will be
reverted in 4.11 and replaced with the proper solution (which was
3846fd9b8600).  Long story short, the issue seems solved, the revert
of PCIe port PM is dequeued.  Perhaps this also fixes the issues in
the bugzilla entry you mentioned above, at least for some laptops?

Thanks,

Lukas
