Title:
resume from suspend issue
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hi,
I am unable to resume from suspend after a fresh install of Ubuntu16.04, and
would like to be able to resume.
The laptop goes into suspend with no problems (screen goes off, HD and
fans stop, power LED periodically flashes). But when attempting to
resume from suspend, the power light and fan both come on, but nothing
else happens (HD LED does not flash, screen does not come on). In
order to get the machine up and running again, I have to hold power
button down for 10s to power off, then hold it down a further 10
seconds (power light flashes on for 1/2 second or so), then I can
power it up with normal short press of power button.
I've tried switching to several new mainline kernels in an attempt to
diagnose the problem, but to no avail. I've tried the following kernels:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8-rc5/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc2-wily/
I've tried 32 and 64 bit installs, both show the same issue.
I have also tried suspend/resume) from recovery console, which shows
same issue.
If I change the kernel command line to include init=/bin/bash then I
can successfully suspend and resume the machine.
I've also tried unloading kernel modules before suspend in order to
find out which one may be at fault, but have not been able to tie it
down to any particular module. I tried booting normally, then
unloading all modules that were not present when booting with
init=/bin/bash (so same set of modules loaded). I then suspended the
laptop, and it failed to resume.
Many thanks,
Stu
