Hi, I have not been keeping up with ubuntu - before 18.04, I've been using only 16.10 to the extent where this issue would show up, and it didn't appear in that release (I would suspend and resume the machine at least twice a week). I would also point out, that I've seen identical symptoms ("Refused to change power state") way back in Linux 3.2 in Ubuntu 12.04, see Ubuntu bug 1007841
In the meantime, I've also noticed a situation (with stock 18.04 kernel) where the NIC would fail after 2nd resume or later - but, see below... As for 4.16-rc7: I've tried 5 boots with 3 suspends each, and while none of them failed after 1st resume, 4 failed after 2nd or 3rd resume. I'm watching for something else now with 4.16-rc7 - it seems the bug is triggered only when the machine is waken up by the lid-open event (about 60% failure rate - and I think all of the successful resumes were 1st resumes after reboot). 0% replication when waking up by power button. I will update repro steps with this info. ** Summary changed: - sky2 gigabit ethernet driver sometimes stops working after resume from sleep (88E8055) + sky2 gigabit ethernet driver sometimes stops working after lid-open resume from sleep (88E8055) ** Description changed: - After resuming from sleep, OCCASIONALLY the NIC is not functional, and - reloading the sky2 module does not work.
