4.10.0-22 No longer suspends on Dell XPS 9560
Status in linux package in Ubuntu:
I have to roll back to -21 to be able to suspend.
Linux XPS 4.10.0-21-lowlatency #23~16.04.1-Ubuntu SMP PREEMPT Tue May
2 14:25:44 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
With -22, it doesn't suspend, and has lots of trouble with it.
I expect to be able to suspend when I close the laptop lid, or when I
go to suspend from the power menu. Instead the OS acts like it
suspends, but the laptop doesn't power down anything. The display
remains on, the fans continue to spin. It acts like it has, because it
takes a bit for the keyboard to respond, and the mouse to move again,
and the wifi was disconnected. It's just that the hardware doesn't
power down at all.
