 Thank you very much!
 
 1. Can you type 't' at the debugger prompt to get a backtrace and post that.
 2. Looks like it is ACPI related, can you disable ACPI and try to boot?
 3. You are booting and i386 kernel that's why you are only seeing this as
    an i386. Can you try booting the amd64 kernel from the amd64 port?
 4. Can you look if there is a bios upgrade for your machine? It might fix
    the ACPI problem.
 
 Anyway, the backtrace will be helpful figuring out why it crashes.
 
 Thanks,
