Feedback on the Dell PowerEdge T110 ii

Asked by Robert Grizilo

OS: Ubuntu 12.04 Server LTS x64
HW: Dell PowerEdge T110 ii

Integrated nic BCM5722 has connectivity issues, from time to time stops working, kicks out from running any session (web, ssh... whatever), and sometimes comes back, sometimes not, and in between you can't connect, you can't even ping.

I've tried to disable all bios IPMI features, but the problem didn't go away.
I've tried on all speeds (10/100/1000) using ethtool, but the problem didn't go away.
I've tried disabling various offload features using ethtool, but the problem didn't go away.
I've installed second nic Intel 82579 and is working perfectly on the same network switch and cables.

After every reboot the bcm5722 is working but then again after fiew minutes behave strange (the LED are showing correct states) and no connectivity.
The server is brand new so I think is not a hardware issue.

ethtool -i eth0
driver: tg3
version: 3.121
firmware-version: 6.2.1 bc 5722-v3.11
bus-info: 0000:02:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes

switched to 10Mbps - not one ping
switched to 100Mbps - 3 of 10 ping pass (randomly)
switched to 1000Mbps - not one ping
the switch is some cisco GbE
with: ethtool -K eth0 rx off tx off - same behaviour
with: ethtool -K eth0 tso off - same behaviour

after limited testing it seems like hardware problem,
same UTP cable moved to some noname USB-NIC (dm9601) and the connection works perfectly.

Thanks for asking this. The T110ii is not yet certified for 12.04 LTS. Because of that, there's not a lot that can really be said. However, I am going to convert this over to a bug, because I think this could be a legitimate bug in the driver.
