I had too many problems with kernel 4.10 to be able to test this, so I just let this report expire. Anyway, I kinda gave up with investigation.
One thing I discovered, and this is to people who may be reading this and looking for a solution, was that suspend with 'sudo acpitool -s' command was working very good! So I just edited my systemd- suspend.service file and modified ExecStart line to look like this: ExecStart=/usr/bin/acpitool -s and thats it. Suspend is now working as it should be. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1641244 Title: Ubuntu 16.04 suspend works only twice or thrice in a row, freezes at next attempt To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1641244/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
