The kernel being testing is 4.10.0-11-generic, I believe a fix may be in Ubuntu-4.10.0-15.17 that may address this issue. We've seen this sort of issue before, e.g. bug 1654073
I believe the pertinent fix is upstream commit: commit 449809a66c1d0b1563dee84493e14bf3104d2d7e Author: Eric Dumazet <[email protected]> Date: Wed Mar 1 08:39:49 2017 -0800 tcp/dccp: block BH for SYN processing ..and this landed in Ubuntu-4.10.0-15.17 as commit 0c244cdf6da6ddeaa4eed2511a75be8f908763aa -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1680349 Title: Ubuntu 17.04: Kdump fails to capture dump on Firestone NV when machine crashes while running stress-ng.
