Well this is odd... I tried following the instructions on PM tracing from https://wiki.ubuntu.com/DebuggingKernelSuspend (using systemctl suspend instead of pm-suspend), but the system hangs on resume when tracing is enabled - and this happens also when pm_test is set to "devices" (doesn't happen with "freezer").
There is no hang when tracing full suspend on 4.8.0. ** Attachment added: "pm_trace of boot after hang with pm_test=devices" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1758507/+attachment/5095301/+files/dmesg-4.16-rc7-test-devices-fail.txt -- 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/1758507 Title: sky2 gigabit ethernet driver sometimes stops working after lid-open resume from sleep (88E8055) Status in linux package in Ubuntu: Confirmed Bug description: After resuming from sleep using the lid-open event, OFTEN (60% replicable, usually after 2nd or later resume) the NIC is not functional, and reloading the sky2 module does not help.

Replicability: When it happens once, further suspend-resume cycles (tried ~5) don't fix it. Reboot fixes the NIC, and it often survives first resume after that, but 1-2 suspend-resume cycles later the issue WILL occur again. Per-boot chance of encountering the issue - so far 2/5.
