--- Comment #8 from Olivier Cochard <oliv...@freebsd.org> --- To sum up, there are 2 problems here: 1). The root cause: After network cable disconnect, the negotiated speed 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=1627816 And the Linux patches that solved it are: e1000e: PCIm function state support: https://lkml.kernel.org/netdev/20190628224932.3389-16-jeffrey.t.kirs...@intel.com/ e1000e: Make speed detection on hotplugging cable more reliable https://lkml.kernel.org/netdev/309b89c4c689e141a5ff6a0c5fb2118b970d7...@orsmsx103.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. -- You are receiving this mail because: You are the assignee for the bug.
