This bug is awaiting verification that the linux-aws/5.15.0-1048.53
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-jammy-linux-aws' to 'verification-done-jammy-
linux-aws'. If the problem still exists, change the tag 'verification-
needed-jammy-linux-aws' to 'verification-failed-jammy-linux-aws'.


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!

Bug description:
  [Impact]
  Hotplugging RJ45 ethernet cable only works for one time because ACPI GPE
  wake doesn't working properly anymore.

  [Fix]
  Always use PME poll to read PCI PME to know if there's wake event.

  [Test]
  With the patch applied, ethernet cable can always be detected.

  [Where problems could occur]
  PME poll mechanism periodically reads the PMCTRL register, so the power
  consumption can be slightly higher. The increase will be very low,
  probably won't be noticeable.
