Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.17 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.

(Nothing happens) Doing it manually also fails, and nothing appears in dmesg: #echo "mem" > /sys/power/state Error while writing to stdout write_loop: Invalid argument And, more interestingly, #cat /sys/power/state freeze disk Using the not-so-good-and-apparently-unsupported #echo "freeze" > /sys/power/state does seem to successfully suspend, however I cannot resume from this (assumed to be a separate issue). Likewise, pm-hibernate seems somewhat functional. I am using a the utopic unicorn kernel compiled from git at kernel.ubuntu.com, with a tiny patch that is required for my keyboard to work (hard to file bug reports without a keyboard). The official kernel behaves identically, as does vanilla 3.17 from the mainline folder of kernel-ppa.
