From bb1d4217e35df43e05176ebce234c4435d9b94f8 Mon Sep 17 00:00:00 2001 From: Ondrej Zary <linux@rainbow-software.org> Date: Thu, 24 Sep 2015 17:02:07 -0500 Subject: [PATCH] PCI: Disable MSI on SiS 761 MSI is broken on SiS 761 chipset at least on PC Chips A31G board. No interrupts are delivered once MSI is enabled for a device. This causes hang on X11 start with a nVidia card installed (with nouveau driver). Disable MSI completely for this chipset.
