That probably just means you did not configure off mode for idle.
Suspend and resume still works for me based on a quick try with -rc7.
I use the following test script to enable idle FYI, then suspend,
and wake-up the system to a key press on serial console.
Also modprobe rtc-twl and rtcwake -m mem -s 5 worked.
