--- Comment #4 from Jason Harvey <alienth at gmail.com> ---
Upgraded kernel again, this time to the intel-drm-next tag on 3.18:

$ uname -a
Linux artoo 3.18.0-997-generic #201412200341 SMP Sat Dec 20 03:42:55 UTC 2014
x86_64 x86_64 x86_64 GNU/Linux


Issue still occurs after resume from suspend:

$ dmesg
[32420.465811] [drm] stuck on render ring
