This might be an interrupt issue. Could you try the following:

11.16.3.3 System Hangs (temporary or permanent)
Most system hangs are a result of lost interrupts or an interrupt storm. 
Chipsets have a lot of problems based on how the BIOS configures interrupts 
before boot, correctness of the APIC (MADT) table, and routing of the System 
Control Interrupt (SCI).
Interrupt storms can be distinguished from lost interrupts by checking the 
output of vmstat -i and looking at the line that has acpi0. If the counter is 
increasing at more than a couple per second, you have an interrupt storm. If 
the system appears hung, try breaking to DDB (CTRL+ALT+ESC on console) and 
type show interrupts.
Your best hope when dealing with interrupt problems is to try disabling APIC 
support with hint.apic.0.disabled="1" in loader.conf.

Or you can enter "set hint.apic.0.disabled=1" on the loader prompt.
