Hi, my Intel Xeon runs on 0% idle ALL THE TIME?

I don't see any non idle processes.

Am I missing something obvios? How do I diagnose this issue?


Also, it is a Hyperthreading CPU:
~  Hyperthreading: 2 logical CPUs

But only displays:
dmesg:cpu0: <ACPI CPU> on acpi0


AND, as I understand I need 1 pseudo-process called idle per cpu. Isn't
that true for HT?

# ps  -auxw|grep idle
root      11 12.1  0.0     0   20  ??  RL   Sat06PM 2064:42.01 [idle]


dmesg:ichsmb0: <Intel 6300ESB (ICH) SMBus controller> port 0x400-0x41f
irq 17 at device 31.3 on pci0

Any help would help :)

Thanks,
