Subject: [patch] PCI: disable the MSI of AMD RS690
Date: Thu, 24 Jan 2008 18:59:04 +0800	[thread overview]
Message-ID: <B90463BC30D2E446BA423D888DC85E501BF78E@sshaexmb1.amd.com> (raw)
In-Reply-To: <5CAB7B5D6F8AB84AA868A46B47A507055D8C1D@sshaexmb1.amd.com>

[-- Attachment #1: Type: text/plain, Size: 1917 bytes --]

This patch recover Tejun's commit
4be8f906435a6af241821ab5b94b2b12cb7d57d8
 because there is one MSI bug on RS690+SB600 board which will lead to
boot failure. This bug is NOT same as the one in SB700 SATA controller,
quirk_msi_intx_disable_bug does not work to SB600. Disablement the MSI
of RS690 is the workaround.

Signed-off-by: Shane Huang <shane.huang@amd.com>


Since there is some word wrapping problem with my mail client MS outlook
if I copy the patch into the text, so I'll also attach the patch as an
attachment. Please check it.
