I bet the sysctl knob cpufreq_curr_sysctl does not require Giant mutex. The
change
https://cgit.freebsd.org/src/commit/?id=3D789f03ceb4076c25766ac94ebbc402674=
526e117
has introduced a sx lock for that.

Can you please remove the sysctl flag `CTLFLAG_MPSAFE` from cpufreq_curr_sy=
sctl
and give it another try ?
