I may have discovered a work-around. I installed the Intel Graphics Linux Installer **for Ubuntu 15.10** onto 16.04 using the instructions found here:

https://allanbogh.com/2016/01/05/ubuntu-16-04-installing-the-intel-graphics-drivers-using-the-intel-graphics-installer-for-linux/

And here:

http://ubuntuhandbook.org/index.php/2015/11/install-intel-graphics-installer-in-ubuntu-15-10/

After several suspend and resumes, I haven't been able to reproduce the bug. During the course of normal usage, and if anything changes, I will add another note.

Scratch that last workaround.

After leaving the computer running, without suspend, for an hour or so and returning, the TTY's were no longer responsive.

According to https://wiki.ubuntu.com/Bugs/FindRightPackage#Suspend_and_Hibernate, refiling this report against the kernel is the way to go for now.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.
