Was a bit euphoric about the workaround.

Suspend does not work even with pm-utils installed.

The machine blanks the display but other than that works continuously. With the lid closed, the laptop might overheat. So this issue is endangering the hardware.

Current workaround: Don't suspend, turn off.

This seems the normal case

Might be TLP related - to test, enable ubuntu budgie backports via budgie-welcome recommendations.

Do a full update. Then uninstall tlp. This will also uninstall the UB meta package "ubuntu-budgie-desktop" - dont worry about that. Before you upgrade to 17.10 just reinstall that package.

If all works - great - although don't know why TLP/systemd/kernel is interfering with your suspend.

If suspend is still broken - then yeah - probably either systemd or kernel related.

Uninstalled tlp -> Sleep works fine

Thanks for the hint.

It means there's a bug on kernel driver with runtime power management enable.
Runtime power management (RPM) is generally favorable because it can prolong your battery time.

This change was made by a bot.

[Wolf Rogner (war-rsb)]

With the latest kernel update Linux 4.10.0-24-generic the issue seems resolved.

Installing tlp -> Suspend to RAM works (at least from what I see in the system log)
