I'm having watchdod timeout problems with the bge driver in 7.4-PRERELEASE on a Tyan S4881 motherboard (the S4881 has 4 Opteron sockets, 2 PCI-E slots, and 3 PCI-X slots, plus VGA and dual Broadcom "bge" GigE ports.) I don't know if this problem also affects the similar Tyan S4882 motherboard, which appears to be much more common. I have a S4882 and can swap it for the S4881 and test this, if anyone is interested (there are a lot things to unplug and unscrew, so I'd rather not if there's no reason for it). I've been able to isolate the problem to the following patches Edit src/sys/dev/bge/if_bge.c Add delta 1.198.2.48 2010.10.08.18.46.02 yongari Add delta 1.198.2.49 2010.10.08.18.51.28 yongari Edit src/sys/dev/bge/if_bgereg.h Add delta 1.73.2.22 2010.10.08.18.46.02 yongari Edit src/sys/dev/et/if_et.c Add delta 1.1.2.9 2010.10.08.19.25.46 yongari Edit src/sys/dev/mii/brgphy.c Add delta 1.70.2.14 2010.10.08.19.00.36 yongari Edit src/sys/dev/mii/brgphyreg.h Add delta 1.10.2.3 2010.10.08.19.00.36 yongari Add delta 1.7.2.6 2010.10.08.20.13.42 yongari Add delta 1.7.2.7 2010.10.08.20.27.51 yongari Add delta 1.7.2.8 2010.10.08.20.31.35 yongari Add delta 1.7.2.9 2010.10.08.20.37.13 yongari Add delta 1.7.2.10 2010.10.08.20.41.15 yongari Add delta 1.7.2.11 2010.10.08.20.44.35 yongari Add delta 1.7.2.12 2010.10.08.20.49.44 yongari Add delta 1.7.2.13 2010.10.08.20.52.47 yongari Add delta 1.7.2.14 2010.10.08.23.14.21 yongari Add delta 1.7.2.15 2010.10.08.23.29.45 yongari Add delta 1.7.2.16 2010.10.08.23.34.45 yongari Reverting if_bge.c, if_bgerec.h, brgphy.c, and brgphyreg.h to the version that existed on 10/7/2010 allows me to do a 7.4-PRERELEASE buildworld/ buildkernel/installkernel cycle and the resulting kernel does not exhibit the watchdog timeout problem. The problem appears only on samba shares exported to a Windows XP Pro client (I've been copying a directory with 17GB of "Ghost" images as a test). The dmesg for a kernel that failed (containing the patches above) is as follows: bge0: <Broadcom NetXtreme Gigabit Ethernet Controller, ASIC rev. 0x002003> mem 0xd0110000-0xd011ffff,0xd0100000-0xd010ffff irq 26 at device 2.0 on pci17 miibus0: <MII bus> on bge0 bge0: Ethernet address: 00:e0:81:58:2d:e3 bge0: [ITHREAD] bge1: <Broadcom NetXtreme Gigabit Ethernet Controller, ASIC rev. 0x002003> mem 0xd0130000-0xd013ffff,0xd0120000-0xd012ffff irq 27 at device 2.1 on pci17 miibus1: <MII bus> on bge1 bge1: Ethernet address: 00:e0:81:58:2d:e4 bge1: [ITHREAD] bge1: link state changed to UP bge1: watchdog timeout -- resetting bge1: link state changed to DOWN bge1: link state changed to UP bge1: watchdog timeout -- resetting bge1: link state changed to DOWN bge1: link state changed to UP bge1: watchdog timeout -- resetting bge1: link state changed to DOWN bge1: link state changed to UP bge1: watchdog timeout -- resetting bge1: link state changed to DOWN bge1: link state changed to UP Mike Squires mikes@siralan.org
