I looked into quirks.c and it seems to be correctly patched.) Unfortunately it doesn't seem to work for me (and I am wondering why as the old v4 version seemed to work ontop of one of the 2.6.29-rc versions): dmesg|grep HT pci 0000:00:00.0: Found disabled HT MSI Mapping pci 0000:00:03.0: Enabling HT MSI Mapping pci 0000:00:09.0: Found disabled HT MSI Mapping pci 0000:00:0e.0: Enabling HT MSI Mapping pci 0000:00:09.0: Found disabled HT MSI Mapping pci 0000:00:0f.0: Enabling HT MSI Mapping pci 0000:00:09.0: Found disabled HT MSI Mapping pci 0000:00:10.0: Enabling HT MSI Mapping pci 0000:00:09.0: Found disabled HT MSI Mapping pci 0000:00:10.1: Enabling HT MSI Mapping Device 09.0 doesn't get enabled (good) but 00.0 also not (bad). Then my Intel HDA cannot use MSI. Regards, Prakash
