https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=296201 Bug ID: 296201 Summary: D50067 ix(4)/ixgbe: Intel E610-XT2 (8086:57b0) hangs in attach_pre (ACI) on amd64; works under Linux ixgbe Product: Base System Version: 15.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: info@thedoctorweb.com CC: erj@freebsd.org, kbowling@freebsd.org Created attachment 272032 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=272032&action=edit dmesg.boot and pciconf FreeBSD 15.0-CURRENT @ bf06074106cf (base of pfSense 2.8.1) with backported commit dea5f973 Hardware: amd64 / Architecture: amd64 Severity: Affects Some People The Intel Ethernet E610-XT2 dual-port 10GBASE-T NIC (PCI 8086:57b0, subdevice 8086:0002, "Intel(R) E610 (10 GbE)") is recognized by the ix(4) driver but the device attach hangs indefinitely in ixgbe_if_attach_pre(), during the firmware Admin Command Interface (ACI) initialization, before any "ixN: <...>" probe banner is printed. The interface never appears. The SAME card on the SAME machine works correctly under Linux (ixgbe), which brings both ports up and links at 10G, so the hardware, NVM and platform/BIOS are confirmed good. This is FreeBSD-driver-specific. Hardware - NIC: Intel Ethernet Network Adapter E610-XT2 (2x 10GBASE-T) pciconf: none@pci0:1:0:0 and :0:1 vendor=0x8086 device=0x57b0 subvendor=0x8086 subdevice=0x0002 rev=0x00 class=0x020000 'Intel(R) E610 10GBASE T' - CPU: AMD Ryzen 5 5600GT - Motherboard: Asus PRIME B550M-A WIFI II - PCIe slot: PCIe x16 slot, Gen3 Software / driver tested (both reproduce the hang, identical symptom): 1) In-kernel ix(4) with E610 support from commit dea5f973d0c8 ("ix/ixv: Add support for new Intel Ethernet E610 family devices", D50067), built against the 15.0-CURRENT @ bf06074106cf source base (this is the pfSense CE 2.8.1 kernel base; uname -K = 1500068). 2) Intel out-of-tree base driver ix-3.4.38 (from Intel Download Center, download 14303), built against the same kernel source. Symptom / behavior - pciconf shows the device as none@ (driver does not bind at boot; the shipped 2.8.1 ix(4) predates E610 IDs). - After kldload of the E610-capable module, the device stays none@ and NO ix banner is printed in dmesg. kldload blocks (kernel thread stuck in attach); with the in-tree build it eventually returns after an internal timeout and the attach fails silently; with ix-3.4.38 it stays stuck. - bootverbose=1 produces no additional ix output: the hang is BEFORE the driver prints anything, i.e. in the early ACI/firmware init in ixgbe_if_attach_pre(). - Setting hw.ix.enable_msix=0 (legacy interrupts) does NOT change the behavior, so it is not an MSI-X delivery issue. Cross-check (decisive) - Booting Ubuntu 26.04 LTS live USB on the SAME machine: the in-tree Linux ixgbe driver attaches both ports and links with no issues. => hardware, NVM/firmware and platform (IOMMU/AMD-Vi, ASPM, Above-4G) are all good; the failure is specific to the FreeBSD ixgbe E610 ACI init path.
