Shows acpi errors that take over the terminal often (even during installation)

CPUs spin like crazy on aarch64 FreeBSD 14.0-RELEASE install on Parallels Apple Silicon. Adding debug.acpi.disabled="ged" to /boot/loader.conf resolves the problem. The solution was suggested by u/MikeKarels on reddit. The link to the post on reddit that led to this bug report being filed is available below:

There is a possible fix in -current (aka main or 15.0).  Could you try a VM using a FreeBSD 15 snapshot?  You should be able to find one in https://download.freebsd.org/snapshots/ISO-IMAGES/15.0/.
