From 1284a061e951115792ceaa8a569269424e2a8875 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Tue, 17 Feb 2009 20:40:09 -0800 Subject: [PATCH] PCI quirk: enable MSI on 8132 David reported that LSI SAS doesn't work with MSI. It turns out that his BIOS doesn't enable it, but the HT MSI 8132 does support HT MSI.
