I see the same message with 2.6.29.2 on a laptop with the same CPU model also with cpufreq_ondemand.
In my case the first hibernate attempt gives the message and succeeds. The system resumes ok.
A further hibernation/resume cycle results in a hang (power cycle required).
It' probably a regression wrt 2.6.28.7 (I'm not sure because with the version upgrade I also changed my DRI driver from fglrx to radeon and also the X.org userspace).
Regards, Fabio
