an side effect on setting hint.apic.0.disabled="1" is that your ps2 keyboard will stop working. this will ofcourse mean you will need an usb keyboard
>How-To-Repeat:
set hint.apic.0.disabled="0" and it hangs during the boot process.
>Fix:
set hint.apic.0.disabled="1" during bootup last line is:
acd0: DVDROM <HL-DT-STDVD-ROM GDR8083N/0L02> at ata-master UDMA33
and for a more permanent solution, after installing the system put
hint.apic.0.disabled="1" into /boot/loader.conf
