Bug Description
With my Surface Pro 3 when I suspend from the GUI 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-
echo "freeze" > /sys/power/state
does seem to successfully suspend, however I cannot resume from this (assumed to be a separate issue).
I am using a modified utopic unicorn kernel compiled from git at kernel.ubuntu.com, with the following patch to enable mykeyboard to work:

The official kernel behaves identically, as does vanilla 3.17 from the mainline folder of kernel-ppa.
WORKAROUND: Use hibernate.
