As far as I can work out I was having the issues described here at the end of last week.
On Friday afternoon I installed Joseph's patched kernel and I am no longer getting my NICs dropping out under heavy load. I would be interested to hear how others have been getting on with this patch? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730550 Title: e1000e in 4.4.0-97-generic breaks 82574L under heavy load.
