The issue occurs when plugging in the cable or unplugging and plugging the cable. Systems tested: Dell PowerEdge T30 server with 1.0.15 firmware Dell PowerEdge T20 server with 1.0.18 firmware Lenovo ThinkPad P52 laptop with 02.25 firmware On both systems the Intel Management Engine is enabled. The problem occurs on both the Gentoo Sources and the Vanilla Soures. Kernels tried: 5.1.5, 5.1.7 and 4.19.48. - Tried different cabling; - Tried using a managed Cisco Catalyst 3650 Compact switch; - Tried using an unmanaged switch; - Tried with Cisco ASA 5506 - Tried appending pcie_aspm=off to the kernel - Tried disabling various options using ethtool -K enp0s31f6 gso off gro off tso off - Tried both compiling it in the kernel and as a module
- Tried using the in-kernel e1000e driver initially and tried using the driver from the Intel website (version 3.4.2.) after with the various kernels to see whether it'd make a difference. All of the above done to exclude options.
The problem occurs on the I218 and I219-LM, both of them being onboard adapters on the devices. The problem does not occur on a Intel 82574L PCI-Express Card, using the e1000e driver too.
