https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=287079 Bug ID: 287079 Summary: PCI devices unavailable on AMD FCH SMBus Controller Product: Base System Version: 14.2-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: vincent@landgrafx.de Created attachment 260720 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=260720&action=edit Contains: b650.jpg dmesg.txt loader.txt pciconf.txt Hi, I'm running FreeBSD 14.2-RELEASE-p1 amd64 on an ASUS TUF GAMING B650-PLUS WIFI (https://www.asus.com/motherboards-components/motherboards/tuf-gaming/tuf-gaming-b650-plus-wifi/) and everything works great except for the Mellanox ConnectX-3 PCIe x4 NIC 10 Gigabit 10GBe SFP+ CX311A that I plan to use in the third slot of the mainboard. The AMD B650 chipset seems to not allow me to access the nic. Other peripherals like the sata or re2.5 GBits nic work without a problem. The specs should match just fine: 1 x PCIe 4.0 x16 @CPU - ASUS SafeSlot Core+ 1 x PCIe 4.0 x16 (max. @x4) @PCH I tried the card in the first slot (where now is an nvidia graphics card) and it works fine. So we can exclude the card for the issue. I suspect it to be related to this message: intsmb0: <AMD FCH SMBus Controller> at device 20.0 on pci0 intsmb0: Could not allocate I/O space device_attach: intsmb0 attach returned 6 intsmb0: <AMD FCH SMBus Controller> port 0xff00-0xff0f at device 20.0 on pci0 intsmb0: Could not allocate I/O space device_attach: intsmb0 attach returned 6 I hope you can help me, thanks for your time.
