I have tested a few more kernels to see if we can narrow down the problem. It works on the newest 3.13.0 generic kernel, built in August, as well as the 3.19 kernel built in April.

The problem has probably been introduced somewhere on the 3.19 line between late .April and late July. I'll try to pin it down later.

Platform hibernation works on the following:

It does not work on:
