Yeah, I tried to contact Scott but it seems like he does not reply to user email (some others have mentioned this as well on the lists). But, I'm not sure about MSI. How would I confirm I'm using it, or disable it? It looks from a bit of googling that one can disable it by adding: hw.pci.enable_msix=0 hw.pci.enable_msi=0 to /boot/loader.conf, and rebooting. Would that do it? But would I lose anything by disabling MSI? I'm still not exactly sure what it does, even after googling a bit... ;) Is there a man page I can look at? Thanks for the help!
