Bug Description

[Impact]
System hangs after played video from TBT storage, and then suspend the system. It enters suspend correctly, but hangs during waking up.

[Fix]
There are 2 commits in upstream which fix this issue.
   95c80bc6952b PCI/PME: Fix hotplug/sysfs remove deadlock in pcie_pme_remove()
   3943af9d01e9 PCI: pciehp: Ignore Link State Changes after powering off a slot

[Test]
Verified on below thunderbolt interface with thunderbolt HDD
01:00.0 PCI bridge [0604]: Intel Corporation JHL6340 Thunderbolt 3 Bridge (C step) [Alpine Ridge 2C 2016] [8086:15da] (rev 02)

[Regression Potential]
Low, both commits have been SRU to Ubuntu Disco 5.0 kernel through stable update, and the fix on remove functions are small and reasonable.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
