Now on my system it seems to be disabled but I'm not sure yet how its=20 determined to be that way. Would be worth for you guys to check what the = sysctl's "hw.pci.enable_msi" and "hw.pci.enable_msix" are set to. I havn't looked into this yet, but I'm pretty sure we added MSI support=20 in the 6.2 -> 7.0 timeframe, so that might have uncovered this chipset=20 bug, and possibly the Promise data corruption one as well. -S=F8ren
