Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.13 kernel[0].

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

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.

Note: it is not an upstream bug.

I can not reproduce it like so:
go to terminal
sudo service lightdm stop

this always works, with 3.11.10, 3.12.14, 3.13.6 and 3.14 rc7

However, when lightdm is running, does not resume.

testing reveals that the bug is linked to lightdm
It is not reproducible when lightdm is not running. When lightdm is running, a wide range of kernels show the resume fail. These kernels do not fail resume when lightdm is not running

I have same model of Toshiba and I am having same problem with Linuxmint 17. Resume from suspend freezing the laptop with blank screen(no backlight on LCD panel).

Follow the upstream bug.perhaps you can help with testing.

I just revert back to Linuxmint 16 kernel on linuxmint 17 and everything working again as expected.

Actually not Linuxmint 16 original kernel. Just downloaded latest saucy kernel from mainline/v3.11.10.11-saucy and installed to my Linuxmint 17 system.

Note: I also tested mainline/v3.15-utopic kernel and unfortunately problem still exist.

The good news is that just an hour ago the Intel engineer and I finished testing the fix, so it will go into the kernel soon (I don't know when). Ubuntu kernel developers will pick it up I expect.

I am following upstream bug report. I saw the progress. I will test mainline kernel after released with this fix, then write here about my result. Thank you for your interest about this very annoying bug.

the patch for this has been added to stable kernels 3.15 and 3.14 so I hope it gets picked up by Ubuntu soon.

This is a note to let you know that I've just added the patch titled

    drm/i915: Avoid div-by-zero when pixel_multiplier is zero

to the 3.15-stable tree which can be found at:

The filename of the patch is:
and it can be found in the queue-3.15 subdirectory.

If you, or anyone else, feels it should not be added to the stable tree,
please let <email address hidden> know about it.
