Trying to downgrade systemd seems to be impossible. As soon as I try an apt install --reinstall systemd=<some version> apt tries to remove half of the system...
I have noticed the issue in the past 15 days, I think, but only had time to look at it more closely right now. Some notes: - Trying to upgrade the kernel to latest 5.0.x via the mainline ppa seems to make no difference. - Issue is somehow erratic. Happens like 70% of the time. In some rare occasions the systems seems to save state and then suspend correctly. - When the issue occurs, the beginning of the hybrid sleep seems OK: big activity on disk to save the state, then the disk is powered down. However at this point, rather than suspending the system re-spins up the disk a couple of times and then halts. System logs show a HuHu unexpected nmi, dazed and confused, but it is unclear to me if it is related to the broken suspend - Plain suspend and plain hybernate seem to work. - Hybrid suspend has worked for years on this 2013 Haswell laptop, which is a Shenker, in fact a Clevo, substantially identical to the System 76 Galago UltraPro. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1825402 Title: Regression.
