This is a problem with the Alder Lake N CPU. You should disable pcid to
stabilize your filesystem, then install sysutils/cpu-microcode-intel to update
your cpu microcode. It works for N305 and N100 CPUs so I'm sure it will work
for yours.

1. Add "vm.pmap.pcid_enabled=0" to /boot/loader.conf (or set the variable
directly from loader if you know how)
2. Reboot
3. Install sysutils/cpu-microcode-intel
4. Remove the pcid line from step 1 if necessary.
5. Add cpu_microcode_load=YES to /boot/loader.conf
6. Add cpu_microcode_name="/boot/firmware/intel-ucode.bin"
7. Reboot
