File this one down to a case of impatience. It turns out it does work
(eventually) on both kernels I ran. It seems to take a bit longer on the
current one, but it does eventually enter hybrid sleep. What's
confusing, and I might file a seperate bug for, is that the screen
initially blanks, then comes back - but the user is not able to interact
with the system - it appears frozen. This lasts long enough that more
impatient types like myself may be tempted to hard power off their
system.

Title:
Lenovo IdeaPad Yoga 13 - pm-suspend-hybrid causes system to crash
Status in “linux” package in Ubuntu:
Invalid
Bug description:
When I try running:
sudo pm-suspend-hybrid, it simply freezes. The whole system is
unresponsive. This is a pretty new 'Intel(R) Core(TM) i7-3537U CPU @
2.00GHz' so I would have thought it was supported, but even if not, it
should not crash.
It seems it is supported though. /sys/power/disk contains sleep as a
supported state.
