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: on cpu3 pcib0: port 0xcf8-0xcff on acpi0 pci0: on pcib0 pcib1: at device 2.0 on pci0 pci3: on pcib1 pcib2: at device 3.0 on pci0 pci4: on pcib2 pcib3: at device 4.0 on pci0 pci5: on pcib3 mxge0: mem 0xd8000000-0xd8ffffff, 0xdfa00000-0xdfafffff irq 16 at device 0.0 on pci5 panic: nexus_add_irq: failed .....

Getting a full copy of a verbose dmesg would be most helpful. 'pciconf -lc' might also help answer the first question. -- John Baldwin State-Changed-From-To: open->feedback State-Changed-By: linimon State-Changed-When: Sat Mar 13 19:56:53 UTC 2010 State-Changed-Why: Note that submitter feedback was requested. http://www.freebsd.org/cgi/query-pr.cgi?pr=130483 State-Changed-From-To: feedback->closed State-Changed-By: jh State-Changed-When: Wed Sep 1 13:13:36 UTC 2010 State-Changed-Why: Feedback timeout. http://www.freebsd.org/cgi/query-pr.cgi?pr=130483 >Unformatted:
