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:
