Bug Description
Recently I replaced Ubuntu 16.04 on my Lenovo Yoga 3 11 with Ubuntu Gnome 17.04 and since then sometimes my Laptop won't suspend when I close the lid. The power led does not blink like it is supposed to do and when I open the Laptop the lockscreen appears but freezes after a short time, followed by a blackscreen until eventually it reappears and allows me to unlock it. After that certain application can not be started anymore and would freeze if they were running before. These include Chrome, Gedit and Gnome System Monitor for example. Also my Laptop will not connect to my WLAN until I restart it.
In syslog I found the line:
"Freezing of tasks failed after 20.005 seconds (18 tasks refusing to freeze, wq_busy=0):"
According to syslog
network-nanaeger
whoopsie
cups-browsed
wpa-supplicant
geoclue
packagekitd
several evolution-related processes
goa-daemon
gnome-software
geary
dropbox
deja-dup-monitor
are responsible.
I tried disabling some of them, but it did not solve the problem.
Update: I tested different Kernel versions in the last days. So far there were no issues with suspend/resume using Kernel 4.8 and 4.9. The problem is present in 4.10 and 4.11.
Update 2: I just encountered this issue with Kernel 4.9.
