>Description:
I attempted an install of the OS from media:

FreeBSD-9.0-RC1-amd64-bootonly.iso

in a virtual machine instance using VirtualBox 4.1.4 on Mac OS X 10.6 running on MacBook Pro.

The installer pretty much fails out of the gate. Here is the output:

===============================================================

ACPI Exception: AE_ALREADY_EXISTS, Unable to install System Control Interrupt Handler (20110527/evevent-137)
acpi0: Could not enable ACPI: AE_ALREADY_EXISTS
device_attach: acpi0 attach returned 6

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address   = 0x70
fault code              = supervisor write data, page not present
instruction pointer     = 0x20:0xffffffff80b05e29
stack pointer           = 0x28:0xffffffff813d9bc0
frame pointer           = 0x28:0xffffffff813d9c00

                        = DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 0 (swapper)
trap number             = 12
panic: page fault
cpuid = 0
Uptime = 1s
Automatic reboot in 15 seconds - press a key on the console to abort

===============================================================

I will investigate whether boot screen ACPI options provide a good workaround.
>How-To-Repeat:
a. Install VirtualBox
b. Create a VM instance. I used 60 G dynamic disk and 1 G ram.
c. Boot from ISO file FreeBSD-9.0-RC1-amd64-bootonly.iso
d. Press ENTER at boot screen, proceed with default install
