Subject: Intel ICH5 APIC, ACPI problems in 2.4
Date: Mon, 11 Aug 2003 13:24:13 -0400 [thread overview]
Message-ID: <3F37D13D.7080309@pobox.com> (raw)
I have a couple uniprocessor ICH5 systems from different vendors, with
similar behavior:
2.6: HyperThreading works, ACPI works, all irqs properly routed
2.4: HT works only works with ACPI enabled, but,
ACPI kills the irq routing for the external PCI slots.
pci=noacpi or whatever doesn't work. !CONFIG_ACPI + "noapic"
fixes irq routing, but then no HT sibling appears.
It seems like kernel 2.4.22-rc is missing some ACPI and possibly some
APIC fixes?
Jeff
