If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The system is configured as PowerNV and running Ubuntu 14.04.03 - I configured 2 copper ports of the adapter and running network stress on it for several hours. I then pulled cable and waited for sometime. - The OS did not detect the link down. Even though the TX/RX traffic stopped on the ports. - Kernel log and dmesg did not have any entry to indicate link down after cable pulled. 0007:00:00.0 PCI bridge: IBM Device 03dc 0007:01:00.0 Ethernet controller: Emulex Corporation OneConnect NIC (Lancer) (rev 10) 0007:01:00.1 Ethernet controller: Emulex Corporation OneConnect NIC (Lancer) (rev 10) 0007:01:00.2 Ethernet controller: Emulex Corporation OneConnect NIC (Lancer) (rev 10) 0007:01:00.3 Ethernet controller: Emulex Corporation OneConnect NIC (Lancer) (rev 10) 0007:01:00.4 Fibre Channel: Emulex Corporation OneConnect FCoE Initiator (Lancer) (rev 10) 0007:01:00.5 Fibre Channel: Emulex Corporation OneConnect FCoE Initiator (Lancer) (rev 10) - ifconfig -a cmd still show link up eth43 Link encap:Ethernet HWaddr 00:90:fa:6e:e0:f2 inet addr:103.1.1.15 Bcast:103.1.1.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:7543074880 errors:1 dropped:9 overruns:0 frame:1 TX packets:5926170683 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:8997647070924 (8.9 TB) TX bytes:7177651764733 (7.1 TB) eth44 Link encap:Ethernet HWaddr 00:90:fa:6e:e0:f3 inet addr:103.1.2.15 Bcast:103.1.2.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:5926170613 errors:1 dropped:0 overruns:0 frame:1 TX packets:7543089239 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7488707854629 (7.4 TB) TX bytes:8619256135370 (8.6 TB) Paul, looking at the source code for the driver in Ubuntu 14.04.3 the driver doesn't log any messages after an update to the link status. The following commit upstream adds this functionality: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=18824894dbec3eb2202fc92d52a0c8bd27c8a63f I'll create a test kernel with this patch applied and will attach it here so you can test this commit - I installed Ubuntu patched kernel - I setup and re-ran the test on Houston adapter. I verified that with the patch link Up/Down events now get logged properly when cable pulls.
