On trying to boot the iso in Vbox both the live system and install to disk I get a kernel panic.
My setup is a triple core phenom 3 gigs of ram running intrepid ibex x64.
I tryed enabling IO APIC in the VBox settings for the VM I'm installing to, this gets rid of the kernel panic.
I just remembered I probably could have used the no-apic command at boot.
Maybe this info can be added to the VBox faq and install guide if you can reproduce the problem I had.
