Subject: [PATCH] pci-quirks: disable MSI on RS400-200 and RS480
Date: Mon, 16 Apr 2007 13:59:18 +0900 [thread overview]
Message-ID: <20070416045918.GI10619@htj.dyndns.org> (raw)
MSI doesn't work on RS400-200 and RS480 requiring pci=nomsi kernel
boot parameter for ahci to work. This patch disables MSI on those
chips.
