I was able to reproduce watchdog timeouts on Dell R820 but I'm not sure you're also seeing the same issue here. Due to unknown reason, it seems programming RX MTU register has no effect with BCM5720 on R820. Receiving frames larger than 175(?) bytes seem to hang the controller on R820. Current workaround for the issue is to set the MTU of sender(i.e. link partner or switch) to some low value, 128 for example. That would show poor performance but shall make your controller work. I asked help to Broadcom and waiting for answers/hint from Broadcom. > bge0: CHIP ID 0x05719001; ASIC REV 0x5719; CHIP REV 0x57190; PCI-E > miibus0: <MII bus> on bge0 > brgphy0: <BCM5719C 1000BASE-T media interface> PHY 1 on miibus0 > brgphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, > 1000baseT-aster, 1000baseT-FDX, 1000baseT-FDX-master, auto, auto-flow > bge0: Ethernet address: 2c:76:8a:54:08:14 > pci0:3:0:1: failed to read VPD data. > bge1: <Broadcom unknown BCM5719, ASIC rev. 0x5719001> mem > 0xf6bc0000-0xf6bcffff0xf6bb0000-0xf6bbffff,0xf6ba0000-0xf6baffff irq 36 > at device 0.1 on pci3 > bge1: APE FW version: NCSI v1.0.80.0 > bge1: CHIP ID 0x05719001; ASIC REV 0x5719; CHIP REV 0x57190; PCI-E > miibus1: <MII bus> on bge1 > brgphy1: <BCM5719C 1000BASE-T media interface> PHY 2 on miibus1 > brgphy1: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, > 1000baseT-aster, 1000baseT-FDX, 1000baseT-FDX-master, auto, auto-flow > bge1: Ethernet address: 2c:76:8a:54:08:15 > pci0:3:0:2: failed to read VPD data. > bge2: <Broadcom unknown BCM5719, ASIC rev. 0x5719001> mem > 0xf6b90000-0xf6b9ffff0xf6b80000-0xf6b8ffff,0xf6b70000-0xf6b7ffff irq 32 > at device 0.2 on pci3 > bge2: APE FW version: NCSI v1.0.80.0 > bge2: CHIP ID 0x05719001; ASIC REV 0x5719; CHIP REV 0x57190; PCI-E > miibus2: <MII bus> on bge2 > brgphy2: <BCM5719C 1000BASE-T media interface> PHY 3 on miibus2 > brgphy2: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, > 1000baseT-aster, 1000baseT-FDX, 1000baseT-FDX-master, auto, auto-flow > bge2: Ethernet address: 2c:76:8a:54:08:16 > pci0:3:0:3: failed to read VPD data. > bge3: <Broadcom unknown BCM5719, ASIC rev. 0x5719001> mem > 0xf6b60000-0xf6b6ffff0xf6b50000-0xf6b5ffff,0xf6b40000-0xf6b4ffff irq 36 > at device 0.3 on pci3 > bge3: APE FW version: NCSI v1.0.80.0 > bge3: CHIP ID 0x05719001; ASIC REV 0x5719; CHIP REV 0x57190; PCI-E > miibus3: <MII bus> on bge3 > brgphy3: <BCM5719C 1000BASE-T media interface> PHY 4 on miibus3 > brgphy3: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, > 1000baseT-aster, 1000baseT-FDX, 1000baseT-FDX-master, auto, auto-flow > bge3: Ethernet address: 2c:76:8a:54:08:17 > > Regards, > > -- > Anders.
