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 v4.5 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.

Hi,
sorry for the delay, this is a friend's laptop. The failure to suspend was there in 4.5.0-040500-generic package, but it is fixed in 4.6.0-040600rc1-generic.

however, a kernel bug with a similar trace as the bug in kernel package 4.4.0-16-generic (see below). All tested versions suffer from flickering in the screen that appears at random intervals. The flickering disappears for a while in version 4.6.0 after a suspend/resume cycle.

I forgot to say that the problem was there from the first boot. Only kernel versions higher than 4.6 can suspend, but flickering and intel display driver bug is present in all versions.
