I am very sorry, but I made a mistake testing this patch. I messed up my kernels and got a false positive and only noticed this now. The patch does NOT work and even makes things worse: dmesg|grep HT pci 0000:00:09.0: Found disabled HT MSI Mapping pci 0000:00:09.0: Enabling HT MSI Mapping pci 0000:00:09.0: Found enabled HT MSI Mapping pci 0000:00:09.0: Found enabled HT MSI Mapping pci 0000:00:09.0: Found enabled HT MSI Mapping pci 0000:00:09.0: Found enabled HT MSI Mapping This is exactly the device which shouldn't be MSI enabled for me. On the other hand, it doesn't enable the needed devices anymore. So please drop this patch.
