Subject: [PATCH][2.4.26 x86_64] fix ACPI PRT entry handling
Date: Fri, 21 May 2004 15:23:22 -0700 [thread overview]
Message-ID: <D621AA393FEB2544B1370005D36B875A05765F86@mail-sc-12.nvidia.com> (raw)
This patch fixes a PCI interrupt routing bug that shows up when running
on x86_64 with ACPI and IOAPIC functionality enabled. Without this patch
in place, the code attempts to route all configurable PCI interrupts to
IRQ 0.
Regards
Andy
