NetXtreme BCM5722 strangeness on Proliant ML115
11:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5722 Gigabit Ethernet PCI Express
With standard squeeze kernel seemingly once a day this nic stops working. Looking at the switch port it seems the nic is
transmitting (or retransmitting) something as fast as possible. A simple ifdown/ifup seems to cure for another day.
On latest backport kernel 3.2.20-1~bpo60+1 (installed today) the nic does seems to be stable. iperf reports 1gb
performance. However the count of dropped packets is slowly growing:
eth0 Link encap:Ethernet HWaddr 00:21:5a:d3:d0:0c
inet addr:192.168.2.10 Bcast:192.168.2.255 Mask:255.255.255.0
inet6 addr: fe80::221:5aff:fed3:d00c/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:8801144 errors:0 dropped:1824 overruns:0 frame:0
TX packets:2263228 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:1257
This issue is present in the firmware nonfree from stable, and backports, and the using the latest source compiled from
broadcom 3.122n. I have changed cables and switch ports. There is another other gigabit nic on the switch is nVidia
Corporation MCP77 and this has no errors or dropped packets.
Anyone else seeing this? How to progress? .. should I log a debian bug, or just go buy an Intel card? Or ? :-)
