How can I figure out what's wrong with the standard boot process?
I can't even log the boot messages since the computer stuck and
not respond.

You could try a verbose boot (equivalent: boot -v) and see _when_
the system stops resonding. It would help to post the error message
(last lines of console output) to the list to get a better impression
about what's happening.

If I remember correctly, "safe mode" refers to the mode with ACPI
disabled, right? In this case, it _could_ be an ACPI problem (a really
wild guess, as you have provided no information about the system you
are trying to boot FreeBSD on).

Thanks for replying!!

Yes, you remember correctly, safe mode disable the ACPI support automatically.

I think it's a problem in the ACPI system because when I disable ACPI, it boot successfully even without choosing safe mode.

But what that is strange here, is that Microsoft Windows and Linux (Debian) are able to boot with ACPI enabled. furthermore, some days ago FreeBSD itself succeeded to boot also with ACPI support enabled.

As for the error messages, there's not a particular error message. it simply stuck during the initialization of the PCI bus.

Here are the last eight lines:

pcib2: <ACPI PCI-PCI bridge> at device 30.0 on pci0
pcib2: domain   0
pcib2: secondary bus    2
pcib2: subordinate bus  2
pcib2: no prefetched decode
pcib2 Subtractively decoded bridge.
pcib2: <ACPI PCI bus> on pcib2
pcib2: domain=0, physical bus=2
