Title: The system cannot resume from S3 if user unplugs the TB16 during suspend state Status in HWE Next: New Status in linux package in Ubuntu: Fix Released Status in linux-oem package in Ubuntu: Fix Released Status in linux-oem-osp1 package in Ubuntu: Fix Released Status in linux-oem source package in Bionic: Fix Released Status in linux-oem-osp1 source package in Bionic: Fix Released Status in linux source package in Eoan: In Progress Status in linux source package in Focal: Fix Released Bug description: [Impact] Unplug TBT dock during S3 and then wakes up the system leads to system hangs. This not only happens on Dell TB16, but also Dell WD19TB. It's more like a BIOS or TBT firmware issue that TBT firmware doesn't re-create the PCIe tunnels. [Fix] Mika provides 4 patches to fix this issue, but only 2 are accepted and are included in linus' tree. We need especially the 4th commit to fix the issue, so we keep the 3rd and 4th commits as sauce patches. [Test] Verified on Dell Precision 5530 + WD19TB [Regression Potential] Low, those patches doesn't change the code path much. The 4th commit adds some checks to return failure state, and it should be safe for those machines which is working well.
