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.
