I've disabled SMP with the kern.smp.disabled=1 sysctl and I'll see what 
happens next. Strangely though the kernel seems to think the system has 
only one cpu despite it being hyperthreaded:

# sysctl -a | grep cpu
kern.threads.virtual_cpu: 1
kern.ccpu: 1948
kern.smp.maxcpus: 1
kern.smp.cpus: 1
hw.ncpu: 1
hw.acpi.cpu.cx_supported: C1/0
hw.acpi.cpu.cx_lowest: C1
hw.acpi.cpu.cx_usage: 100.00%
machdep.cpu_idle_hlt: 1

# sysctl -a | grep machdep.hlt_logical_cpus
(no results)

# dmesg | less

I'll try disabling ACPI if I have to reboot the server once more.
