Title:
Kernel 4.9+ regression: Suspend - Freezing of tasks failed
Status in linux package in Ubuntu:
Confirmed
Status in systemd package in Ubuntu:
Confirmed
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.
