From 0e565652857c8f01d2fe7061ec7bb82cb6ee3460 Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Sun, 29 Jan 2012 12:41:15 +0100 Subject: [PATCH 20/87] firewire: ohci: disable MSI on Ricoh controllers commit 320cfa6ce0b3dc794fedfa4bae54c0f65077234d upstream. The PCIe device FireWire (IEEE 1394) [0c00]: Ricoh Co Ltd FireWire Host Controller [1180:e832] (prog-if 10 [OHCI]) is unable to access attached FireWire devices when MSI is enabled but works if MSI is disabled. http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg28251.html Hence add the "disable MSI" quirks flag for this device, or in fact for safety and simplicity for all current (R5U230, R5U231, R5U240) and future Ricoh PCIe 1394 controllers.
