From c0613ff21bef2595aebd8f33f36e52a7528e8cb0 Mon Sep 17 00:00:00 2001

Subject: [PATCH] PCI: Disable MSI for MCP55 on P5N32-E SLI
As reported in <http://bugs.debian.org/552299>, MSI appears to be
broken for this on-board device. We already have a quirk for the
P5N32-SLI Premium; extend it to cover both variants of the board.
