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] It's not root caused yet by Intel, so disable the s0ix flow on X1 Carbon 7th as a temporary workaround. [Test] After applying the DMI quirk patch, e1000e keeps working, so it doesn't block s2idle anymore. User also confimred the workaround works. [Regression Potential] Low. It limits to a specific model, and I can confirm s0ix can still be reached withouth this feature. === Original Bug Report === 5.4.0-16 and 5.4.0-17 go to suspend when the lid is closed, but *only once* after boot. On subsequent attempts, when the lid it closed, backlight and wifi are turned off, but system does not suspend.
