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

[Fix] Instead of using the supported speeds to determine whether to wait for Link training, check whether the port supports DLL Link Active reporting. The ports in question do not, so we'll wait only the 100 ms required for Ports that support Link speeds <= 5 GT/s. This of course assumes these Ports always train the Link within 100 ms even if they are operating at > 5 GT/s, which is not required by the spec. [test] With the patch, the total time s3 resume is 4454.244 ms which is smaller than 5s. [Regression Potential] Low. Follow the PCI spec to check whether the device supports DLL Link Active reporting, then choose the time of delay.
