Notifiers are used from the cpufreq core when frequency is changed.
And the powersave governor should have changed the frequency only
ONCE, i.e. to go to lowest frequency.

So, it probably happened at the first & only change at that time as well..
But it shouldn't happen any later. So, see what the log looks like on
that crash.
