A very interesting observation. Running "ethtool --test eno7 offline" fixes the link. "ip link set dev eno7 up && ethtool -t eno7 offline" also works. link comes up fast and stays up. However if link is unplugged/disabled on switch and plugged in/turned back on, it starts looping again. Link detection timing issue? ------------------------------------------------------------------------------ _______________________________________________ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel To learn more about Intel® Ethernet, visit http://communities.intel.com/community/wired
