I can confirm that recent changes in FreeBSD have led to this issue. In
fact, everything was functioning correctly when I was using FreeBSD 14
Current from two weeks ago. This is unrelated to the updates in the
Raspberry Pi firmware, as I manually replaced the latest firmware and htop
was displaying temperature and frequency accurately. However, everything
went awry after installing alpha1 today. I am using a Raspberry Pi 4B 8GB
version 1.5.

Below is the compilation log of my kernel and world. At least the system
compiled from the source code on that day was working fine, so it should be
the recent change that has affected the outcome.
