After looking at the code, the messages related with the DMA errors and registers dump should be harmless. The tg3 driver dumps these logs while the device is not yet initialised (there are patches yet to be accepted mainline to remove these logs when device is not up yet).
The fact that there is no traffic passing through this interface is more important, and should be a different issue. You seem to have 3 ethernet devices, 2 are using tg3 driver and another usb device. Could you please describe how you're trying to send packets through the interface? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/961239 Title: Broadcom NIC (tg3) not working with DMA errors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/961239/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
