Date: Fri, 11 Sep 2015 23:12:17 +0200 From: Ondrej Zary <linux@...nbow-software.org> To: Bjorn Helgaas <bhelgaas@...gle.com> Cc: linux-pci@...r.kernel.org, Kernel development list <linux-kernel@...r.kernel.org> 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.
