Hi, Sorry about being unclear. They all failed in the same way. So, these combinations have continuous timeout errors and fail to completely boot: Plain 9.0-RC1 9-stable with 1.62 of mfi.c 9-stable with www.freebsd.org/~jhb/patches/mfi.patch, pci_alloc_msi instead of pci_alloc_msix and hw.mfi.msix=0 This boots, but gets "mfi0: Cannot allocate interrupt" and there are no /dev/mfi* devices: 9-stable with www.freebsd.org/~jhb/patches/mfi.patch and hw.mfi.msix=1 This seems to work, but I have not put any load on it yet: 9-stable with www.freebsd.org/~jhb/patches/mfi.patch, pci_alloc_msi instead of pci_alloc_msix and hw.mfi.msix=1 I see you have a new patch, www.freebsd.org/~jhb/patches/mfi_msi.patch. This patch doesn't seem to include the dummy read from your earlier patch, or the one in 1.62 of mfi.c. I assume I need to apply the 1.62 mfi.c diff to by 9-stable sources as well. Is that correct? Will test out the new patch.
