Bernard, I've some quick suggestions from my colleague Narendra here at Dell to pass on. First try disabling TSO. If that doesn't work, disable both GSO and TSO. ethtool can be used to disable both GSO and TSO.
Also, I can't see what firmware version you have on the NIC. Can you verify that it's the latest? It's available at http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=VPY7Y Narendra also noted that there have been a couple of related bugs recently, though I believe those are in 3.16-rc1: tg3: Fix data corruption on 5725 with TSO <https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/net/ethernet/broadcom/tg3.c?id=0f0d15100a8ac875bdd408324c473e16d73d3557> tg3: Expand 4g_overflow_test workaround to skb fragments of any size <https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/net/ethernet/broadcom/tg3.c?id=375679104ab3ccfd18dcbd7ba503734fb9a2c63a> -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1331513 Title: 14e4:165f tg3 eth1: transmit timed out, resetting on BCM5720 To manage notifications about this bug go to: https://bugs.launchpad.net/dell-poweredge/+bug/1331513/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
