I've just tested on Eoan with the proposed branch. It didn't resolve my issue. I'll give it some time today to see if the new kernel gets released.
This is the kernel I'm running after an apt update/upgrade cycle this morning Linux MiX 5.3.0-43-generic #36-Ubuntu SMP Mon Mar 16 13:29:01 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1865570 Title: suspend only works once on ThinkPad X1 Carbon gen 7 Status in linux package in Ubuntu: Triaged Status in linux-oem-osp1 package in Ubuntu: New Status in linux source package in Bionic: Won't Fix Status in linux-oem-osp1 source package in Bionic: New Status in linux source package in Eoan: New Status in linux-oem-osp1 source package in Eoan: Won't Fix Status in linux source package in Focal: Triaged Status in linux-oem-osp1 source package in Focal: Won't Fix Bug description: === SRU Justification === [Impact] Lenovo X1 Carbon 7th can only susped (s2idle) once, subsquent suspends are blocked by failed e1000e resume routine. [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.
