Sable does not resume from suspend (Intel i7 HD4000)

[Jason Gerard DeRose]

This is a regression from 3.8.0-18, and is present in both 3.8.0-19 and 3.8.0-20.

Resuming from supsend no longer works on the System76 Sable Complete all in one. When you wake up the system (either with the power button or keyboard), the hardware status will change (power light goes from blinking to solid), but the system does not resume. The backlight stays off, and I'm unable to SSH into the system. By watching our DHCP server logs, I can also confirm that the system never makes a DHCP request. So the issue is something more that just the backlight not being turned on.

Interestingly, if you happen to have a 2nd monitor connected (over HDMI), the system resumes from suspend perfectly. But if you then disconnect the 2nd monitor and try again, it wont resume.

A bit more digging... this is more than just the backlight not being turned on. I installed openssh-server to see if I could SSH into the system when the screen was black (after attempting to wake up)... no such luck.

And by watching our DHCP server logs, I've confirmed that this system never makes a DHCP request. The the resume process is hanging early on.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.9 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'.

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.

We tested with the 3.9 mainline kernels, and this bug exists there as well.
