2.6.23-stable review patch. If anyone has any objections, please let us know. ------------------ From: Alan Cox <[EMAIL PROTECTED]>
patch 96c2a8766bf4fe91abac863749c11637fabcc64f in mainline. When PCI IDE controller works in legacy mode and no PRT entry is found in ACPI PRT table, OSPM will neither read the irq number from the IDE PCI configuration space nor call the function of acpi_register_gsi to register gsi. http://bugzilla.kernel.org/show_bug.cgi?id=5637 Signed-off-by: Alan Cox <[EMAIL PROTECTED]> Signed-off-by: Zhao Yakui <[EMAIL PROTECTED]> Signed-off-by: Zhang Rui <[EMAIL PROTECTED]> Signed-off-by: Len Brown <[EMAIL PROTECTED]> Signed-off-by: Greg Kroah-Hartman <[EMAIL PROTECTED]> --- drivers/acpi/pci_irq.c | 9 +++++++++ 1 file changed, 9 insertions(+) --- a/drivers/acpi/pci_irq.c +++ b/drivers/acpi/pci_irq.c @@ -429,6 +429,15 @@ int acpi_pci_irq_enable(struct pci_dev * &polarity, &link, acpi_pci_allocate_irq); + if (irq < 0) { + /* + * IDE legacy mode controller IRQs are magic.
