Created attachment 261137 [details] dmesg output from the affected system After upgrading to 14.3-RELEASE, there's a page fault in kernel mode during boot.

It's a firmware bug. These would happen before, but we used to silently ignore them. They can be safely ignored. You can disable them by setting hw.efi.print_faults to 0. I've actually been meaning to collect more reports about these, could you attach the output of sysctl machdep.efi_map please?
