Sometime in the past 6 months I lost the ability to suspend my ThinkPad
T520. I don't often suspend this system, so I just noticed it today when I
had it away from AC power for a while. It used to work just fine.
10.1-STABLE FreeBSD 10.1-STABLE #0 r280293: Fri Mar 20 11:28:08 PDT
2015     root@rogue:/usr/obj/usr/src/sys/GENERIC  amd64

When I attempt a suspend, I get errors from both graphics and disks.
drmn0: GEM idle failed, resume might fail
acpi0: device_suspend failed

Anyone have any ideas on what broke?
