Previously, on Intel ICH5, I had to either disable CONFIG_ACPI (which makes my 2nd HT CPU disappear) and boot with 'noapic', or disable CONFIG_SMP and boot with pci=noacpi. If I did not do this, interrupts to the PCI slots would never be delivered. With this update, 2.4 now matches 2.6 behavior: full hyperthread, and interrupts routed correctly. Jeff
