With the freeze patch installed and the power button patch in the kernel it can still fail to stay suspended. However I think there are two causes in my system and without them it will stay frozen at least until there is a power glitch:
- Bluetooth on, even with nothing paired, is certain to cause return from freeze
- Some things on USB can cause return from freeze (I had a USB hub and a card reader dongle and removed them both so I don't know which did it). Note that my Microsoft wireless mouse & keyboard (which has a tiny USB transceiver) does not cause any trouble.

Title:
  Can't suspend on Surface Pro 3

Status in linux package in Ubuntu:
  Incomplete

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-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).

  I am using a modified utopic unicorn kernel compiled from git at kernel.ubuntu.com, with the following patch to enable mykeyboard to work:
  http://www.spinics.net/lists/linux-input/msg34918.html

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

  WORKAROUND: Use hibernate.
