Subject[patch 015/114] PCI quirk: enable MSI on 8132
2.6.28-stable review patch.  If anyone has any objections, please let us know.


From: Yinghai Lu <>

commit e0ae4f5503235ba4449ffb5bcb4189edcef4d584 upstream.

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.
Add quirk to enable it
