I've been running 7.X on a Tyan S4881 (4 dual-core Opteron CPUs) since nearly the beginning of the 7.X cycle, and have just started to see watchdog timeouts on the Broadcom bge0 GigE port. This occurs with a kernel and world compiled on 11/22, and also with a kernel compiled on 11/11 with the 11/22 world. The errors occur when copying a large number (200-300GB) of files over a GigE network to a WD USB drive attached to a PC running XP. There are no Ethernet errors other than those caused by the timeouts. The system uses an nVidia PCI-Express video board and an LSA 300-8X SATA card which have not given any problems. I have not been able, however, to add a SCSI card and I've tried every Adaptec and LSI PCI, PCI-X, and PCI-Express card available to me. The problem appears to be a mismatch of the interrupt expected by the card and the interrupt provided by the board. I haven't found a solution for that problem (yet). The error is the usual watchdog timeout: Nov 27 15:34:11 superxeon kernel: bge0: watchdog timeout -- resetting Nov 27 15:34:11 superxeon kernel: bge0: link DOWN Nov 27 15:34:11 superxeon kernel: bge0: link state changed to DOWN Nov 27 15:34:15 superxeon kernel: bge0: link state changed to UP I intend to switch over to an Intel Pro1000 card since I saw the same problem some timea ago on another box and switching GigE hardware solved the problem. uname -a: FreeBSD superxeon.familysquires.net 7.4-PRERELEASE FreeBSD 7.4-PRERELEASE #12: Mon Nov 22 15:45:36 EST 2010 root@superxeon.familysquires.net:/usr/obj/usr/src/sys/OPTERON8 amd64 dmesg output for bge0/1: bge0: <Broadcom NetXtreme Gigabit Ethernet Controller, ASIC rev. 0x002003> mem 0 xd0110000-0xd011ffff,0xd0100000-0xd010ffff irq 26 at device 2.0 on pci17 bge0: Reserved 0x10000 bytes for rid 0x10 type 3 at 0xd0110000 bge0: CHIP ID 0x00002003; ASIC REV 0x02; CHIP REV 0x20; PCI-X miibus0: <MII bus> on bge0 bge0: bpf attached bge0: Ethernet address: 00:e0:81:58:2d:e3 bge0: [MPSAFE] bge0: [ITHREAD] bge1: <Broadcom NetXtreme Gigabit Ethernet Controller, ASIC rev. 0x002003> mem 0 xd0130000-0xd013ffff,0xd0120000-0xd012ffff irq 27 at device 2.1 on pci17 bge1: Reserved 0x10000 bytes for rid 0x10 type 3 at 0xd0130000 bge1: CHIP ID 0x00002003; ASIC REV 0x02; CHIP REV 0x20; PCI-X miibus1: <MII bus> on bge1 bge1: bpf attached bge1: Ethernet address: 00:e0:81:58:2d:e4 bge1: [MPSAFE] bge1: [ITHREAD] bge0: link state changed to UP Mike Squires mikes@siralan.org
