From 801471436efd7cfa4cefc7af40c6db015e49a450 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Sat, 6 Feb 2016 13:03:21 +0100 Subject: southbridge/intel/bd82x6x/acpi: Fix IRQ warnings The PCIe slot uses Message Signaled Interrupts (MSI) as the IGD does and doesn't use hardware INT lines. Adding the IRQ entry for PEG slot fixes a warning showing up in GNU/Linux dmesg.
