Hi. I'm using FreeBSD/i386 6-stable on HP DL360G5 server, and getting "Watchdog timeout" & "link state changed to DOWN/UP" messages shown below. bce0: /usr/src/sys/dev/bce/if_bce.c(5000): Watchdog timeout occurred, resetting! bce0: link state changed to DOWN bce0: link state changed to UP [System I'm using:] * CPU Xeon 51xx, * Intel 5000X chipset * NIC: bce (1.2.2.6 2006/10/24) bce0: <Broadcom NetXtreme II BCM5708 1000Base-T (B1), v0.9.6> mem 0xf8000000-0xf9ffffff irq 16 at device 0.0 on pci3 bce0: ASIC ID 0x57081010; Revision (B1); PCI-X 64-bit 133MHz miibus0: <MII bus> on bce0 brgphy0: <BCM5708C 10/100/1000baseTX PHY> on miibus0 brgphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseTX, 1000baseTX-FDX, auto bce0: Ethernet address: 00:18:71:73:c5:5a [Tests] Give UDP generating load (ports/net/rude was used). Test configuration: [FreeBSD]-(bce)--- 100BaseTX-switch ---(em)[FreeBSD] packet genarator --------------> packet receiver 70Mbps UDP, 1400Byte packet * 6000pps. Then, the above "Watchdog timeout" message occurs _SOMETIMES_. Maybe once a week, sometimes 10times/day. I've tested with 3 hardware(all HP DL3x0 server with BCM5708 chip), and all of them seems to suffer with this. I've suspected new bce-NIC, and tried with bge cards (also with FreeBSD 6-stable). However, similar message also happens with bge(other network IFs also). Next, I've tried with other cable, other ether-switch, but they still seems to happen _sometimes_. Are these "Watchdog timeout" events common and happening everywhere else? Or am I doing something wrong? Searching the -stable archive, there seems some other people suffering with this: 2006.11.29 [Re: Dell PE 1950 bce NICs revisited] http://lists.freebsd.org/pipermail/freebsd-stable/2006-November/031116.html 2006.12.14 [em watchdog timeout] http://lists.freebsd.org/pipermail/freebsd-stable/2006-December/031416.html Thank you. -- KAWAGUTI Ginga
