Can you please try "echo test > /sys/power/disk" before the hibernation? After that "echo disk > /sys/power/state" should only "suspend" the box for several seconds and come back to the command prompt. If that fails, please try # echo testproc > /sys/power/disk # echo disk > /sys/power/state and see if this returns to the command prompt.
