Hello,
I can reproduce the problem here:
- FreeBSD 5.2.1-RELEASE-p4 #0: Wed Apr 14 22:06:33 CEST 2004 i386;
- Single processor, Hyperthreading *enable*;
- dmesg:
Preloaded elf kernel "/boot/kernel/kernel" at 0xc0aa6000.
Preloaded elf module "/boot/kernel/acpi.ko" at 0xc0aa626c.
ACPI APIC Table: <PTLTD APIC >
Timecounter "i8254" frequency 1193182 Hz quality 0
CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz (3000.12-MHz 686-class CPU)

- vmstat/iostat/top all fail to report CPU usage;
- This seems to be an SMP specific problem since I have an other machine
with an identical level release, but which a single processor *without*
Hyperthreading.
Note: I think this problem may be related to Problem Report bin/60385.
