At least the likelihood is big and the "saving" to narrow down bisecting just to
the cpufreq patch is small compared to the "cost" of the risk of an unwanted side effect.
OTOH not sure when I find a time frame for the bisect nightmare.
That's why I tweaked my s2ram script in this way:

+       if [[ "$1" = "mem" && "$(uname -r)" = "3.10.0" ]]; then
+               echo " tweak governor ..."
+               for g in performance ondemand; do
+                       for i in 0 1 2 3; do
+                               echo $g > /sys/devices/system/cpu/cpu$i/cpufreq/scaling_governor
+                       done
+               done
+               echo 1 > /sys/devices/system/cpu/cpufreq/ondemand/ignore_nice
+       fi
