Hi all,
I've got a system that has two hyperthread-capable Xeons. If I boot it
with 2.6.10 it shows up as 4 cpus, but with 2.6.14 it only shows 2 cpus.
The relevent boot logs are:
2.6.10:
DMI 2.3 present.
ACPI: LAPIC (acpi_id[0x01] lapic_id[0x00] enabled)
Processor #0 15:2 APIC version 20
ACPI: LAPIC (acpi_id[0x02] lapic_id[0x06] enabled)
Processor #6 15:2 APIC version 20
ACPI: LAPIC (acpi_id[0x03] lapic_id[0x01] enabled)
Processor #1 15:2 APIC version 20
ACPI: LAPIC (acpi_id[0x04] lapic_id[0x07] enabled)

You snipped the important part of the log. It's not using ACPI in 2.6.14
for some reason, which you need for HT to be detected. Either you didn't
configure it in or it's failed to enable somehow. Please post the entire
dmesg.
