    This is great info.  One thing, what do you mean by 'KVM'?  What
    is DragonFly running under, exactly?
Q
    I think once I understand the environment I may be able to figure out
    why the acquisition loop is blowing up.

As Freddie says I'm running the QEmu KVM software on Ubuntu x64. 
DragonFly is running 32bit with 3.5Gb RAM and 4 CPUs (AMD-Phenom). 

I can also trigger SMP DragonFly to lock up during a buildworld on 
VMWare Server 1.0.5 (Dual Core, 2Gb RAM) and VirtualBox. I haven't tried 
the bare metal but could do so if anyone thinks it would be useful. I'm 
running HEAD as of yesterday but 1.12.2 also locks up.

The kernel is GENERIC with "options SMP" and "options APIC_IO" enabled 
and no modifications to /etc/make.conf. I have also tried enabling 
"options ACPI_QUIRK_VMWARE".

For debugging I copied the kernel and source to my Ubuntu home directory 
and ran.

kvm -smp 4 -m 3500 -hda "~/img/dfly.img" -net nic,model=e1000,vlan=1 
-net user,vlan=1 -redir tcp:2201::22 -s
gdb -s kernel.SMP -d ~/source/
(gdb) target remote localhost:1234
(gdb) c
