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] Enable ACS quirk on Intel CML root port. [Test] With the patch applied, Intel NVMe mostly works after S3. There's still a 1/1000 chance the issue happens. Intel is investigating the root cause. [Regression Potential] ACS works at hardware level, so I can't really assess the risk of regression. Since Intel confirmed CML also needs ACS quirk, we can only trust them until they devise a real fix.
