Hi Zack,
Silly me, its not possible to compile SMP image without CONFIG_ACPI_BOOT (a lot of SMP detection code is linked to basic ACPI infrastructure).
Can you please try the nolapic/noapic boot options? They should disable the APIC, and if APIC is the "root" of your crashes, we will find out that way.
