Cannot make a MacBookPro 11,1 suspend.

1. When putting the lid down, acpi_listen prints:

$ acpi_listen
button/lid LID close
button/lid LID open

... so the lid is signalling correctly. Upon opening, the screensaver prompt is present, and typing in the password brings me back to the desktop. Nothing is found in dmesg.

2. When choosing "suspend" from the top-right power menu, the screen goes black and shortly lights up again, showing the screensaver login prompt. Typing in the password brings me back to the desktop as if nothing had happened.

3. To remark that the power menu in the System Settings shows sometimes "Suspend" as greyed out, and hibernate is not listed. Perhaps this is related to the suspend process taking very long (minutes) as reported in other bugs, but I have never waited so long to find out.

4. When attempting to hibernate instead, using:

$ sudo pm-hibernate

... something similar to triggering a suspend happens, but this time dmesg lists one error:

[ 1434.487141] [drm:hsw_unclaimed_reg_clear] *ERROR* Unknown unclaimed register before writing to 2030

The whole relevant part of the dmesg is below, containing the sequence towards hibernation and then the sequence towards power up, cropped at the CPUs.

Any hints towards getting suspend or hibernate working would be very appreciated.
