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- xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed- xenial'. 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.

Test when no ethernet gets plugged. Powertop shows power consumption is roughly 5.5W. lspci shows the device is in D0. With the patch, The power consumption is reduced to 1.8W. lspci shows the device is in D3, PME# is correctly enabled. Plug ethernet cable can corretly wake up the device. Unplug the cable, the device gets suspended to D3 correctly. [Regression Potential] Medium. - r8169 is so ubiquitous, with lots of different chip versions. It's hard to test all of them. - PCI D3 needs system firmware (ACPI) support, this might hit some plaform bugs. - the code is still in v4.16-rc*, so it's not well tested by end users.
