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

There is no interrupt while plug/unplug Ethernet cable after S3, so it looks like a regression after 4.15.0-33.36. [Fix] Check changelog and found there are 2 commits introduced from 4.15.0-35.38 might be suspicious * r8169 no internet after suspending (LP: #1779817) - r8169: don't use MSI-X on RTL8168g - r8169: don't use MSI-X on RTL8106e And check the upstream log and found the 2 MSI-X commits had been all reverted, since below commit claims it fixes the MSI-X interrupt issue which is already in Bionic kernel. 083874549fdf PCI: Reprogram bridge prefetch registers on resume So, I reverted the 2 MSI-X commits and found the Ethernet works again after S3. [Regression Potential] Low, the 2 disable MSI-X commits are workarounds, and now we have proper way to fix the issue, so it should be fine to revert them.
