(In reply to Sreehari S from comment #12)
I think that this issue certainly related to CPU frequency, because
dev.cpu.0.freq_levels and dev.cpu.0.freq are looked very different than in the
versions before 13, and in 13 with hint.hwpstate_intel.0.disabled=1

details are in the https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248659

In my case sometimes system hangs even during kernel boot, last messages in
console about USB devices.
