After contacting with engineers of Myricom, they suggest to disable message signaled interrupt (MSI) in /boot/loader.conf and these NICs can work now. " hw.pci.enable_msix=0 hw.pci.enable_msi=0 " However, MSI is really very important for high speed data transmission. Huge number of packets generate many interruptions. Considering that Fedora 9 works well on the same computer, it may be a bug of FreeBSD. Below is the screen when kernel panic occurs. ...... p4tcc3: <CPU Frequency Thermal Control> on cpu3 pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0 pci0: <ACPI PCI bus> on pcib0 pcib1: <ACPI PCI-PCI bridge> at device 2.0 on pci0 pci3: <ACPI PCI bus> on pcib1 pcib2: <ACPI PCI-PCI bridge> at device 3.0 on pci0 pci4: <ACPI PCI bus> on pcib2 pcib3: <ACPI PCI-PCI bridge> at device 4.0 on pci0 pci5: <ACPI PCI bus> on pcib3 mxge0: <Myri10G-PCIE-8A> mem 0xd8000000-0xd8ffffff, 0xdfa00000-0xdfafffff irq 16 at device 0.0 on pci5 panic: nexus_add_irq: failed .....
