Hello
I've got a new Dell Precision workstation here with a BCM5761 on intel
mobo for westmere xeons that is wedging with interrupt storm and will
lockup the system randomly. I have turned HTT and auto powermanagement
off in bios (system cannot sleep), lowest cpu acpi state is C1.
Here is dmesg:
bge0: <Broadcom NetXtreme Gigabit Ethernet Controller, ASIC rev.
0x5761100> mem 0xf3be0000-0xf3beffff,0xf3bf0000-0xf3bfffff irq 17 at
device 0.0 on pci6
bge0: CHIP ID 0x05761100; ASIC REV 0x5761; CHIP REV 0x57611; PCI-E
miibus0: <MII bus> on bge0
brgphy0: <BCM5761 10/100/1000baseTX PHY> PHY 1 on miibus0
brgphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT,
1000baseT-master, 1000baseT-FDX, 1000baseT-FDX-master, auto, auto-flow
Here is pciconf -lv:
bge0@pci0:6:0:0: class=0x020000 card=0x026d1028 chip=0x168114e4
rev=0x10 hdr=0x00
vendor = 'Broadcom Corporation'
device = 'Broadcom 57XX Gigabit Integrated Controller (BCM5761)'
class = network
subclass = ethernet
here is the setup in rc.conf:
ifconfig_bge0="polling -tso -vlanhwtso -vlanhwtag -vlanmtu inet
192.168.123.124 netmask 255.255.255.0"
I have the card plugged into a dlink DSS8 100mbps switch with one
other 100mbps device on it (rich man's crossover cable).
Before turning off TSO4 and VLAN tagging (because I don't use them),
the card would do several things:
1. 1 out of 3 reboots: Fail to bring interface up. ifconfig would hang
and systat/vmstat showed 800+ interrupts per second on IRQ256
2. After a few hours lock up the system, requiring hard reboot
After disabling TSO4 and VLAN stuff:
bge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=80083<RXCSUM,TXCSUM,VLAN_HWCSUM,LINKSTATE>
media: Ethernet autoselect (100baseTX
<full-duplex,flowcontrol,rxpause,txpause>)
Everything seemed fine for about two weeks and then suddenly started
acting up again, locked up, after hard reboot, soft reboot, link will
not come up and I see interrupt storm again....
I am close to buying an intel card to replace the bcm, but then I
noticed that the main intel desktop PCI-E card is 82574L-based and
people are having em driver wedging on that too. So now I have broken
ethernet on this box; my primary link is atheros 5212 pci card and I
may be out of pci slots (or else I might try a pci intel card).
