I've disabled the audio driver and booted up the system. This seems to do the trick, NetBSD will at least boot into the installer program. What would be my next step? if I want to pursue finding the root cause of this issue?
Rebooting with command: boot cdrom netbsd -c
Boot device: /pci@1e,600000/pci@0/pci@1/pci@0/ide@1f/cdrom@0,0:f File and args: netbsd -c
