Unrelated but might be helpful though.

Where do you see there is a problem with the sound btw?

To the OP, please provide at first an output from those commands:

sysctl dev.cpu
sysctl dev.powernow
sysctl dev.acpi_throttle

If there is something from both dev.powernow and dev.acpi_throttle,
please check what driver is actually faulty by disabling one.

For exemple, putting that line:
hint.acpi_throttle.0.disabled="1"
onto /boot/loader.conf
will disable acpi_throttle.
The same apply for powernow:
hint.powernow.0.disabled="1"

Note that a verbose dmesg (boot -v) might be helpful also.

Cheers,
