https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D274926 --- Comment #8 from Olivier Cochard <olivier@freebsd.org> --- To sum up, there are 2 problems here: 1). The root cause:=C2=A0After network cable disconnect, the negotiated spe= ed is 10 Mbps in place of 1Gbps. Notice there are multiple reports of this same 10Mbps negotiation bug (after sleep or disconnection) on Linux with same chipset. Power management seems = to be the culprit on Linux: https://bugzilla.redhat.com/show_bug.cgi?id=3D1627816 And the Linux patches that solved it are: e1000e: PCIm function state support: https://lkml.kernel.org/netdev/20190628224932.3389-16-jeffrey.t.kirsher@int= el.com/ e1000e: Make speed detection on hotplugging cable more reliable https://lkml.kernel.org/netdev/309B89C4C689E141A5FF6A0C5FB2118B970D75A2@ORS= MSX103.amr.corp.intel.com/T/ 2). The second bug with netif restart that trigger a panic, and the text version of the core dump is requested to get more clue about this one. --=20 You are receiving this mail because: You are the assignee for the bug.=
