Hello Bjorn, Hope you are doing well. I am Chaitanya from the linux graphics team in Intel. This mail is regarding a regression we are seeing in our CI runs[1] on linux-next repository. Since the version next-20250221 [2], we are seeing that some of the machines in our CI are unable to connect through ssh (and therefore unable to participate). Looking at the logs we see this. ````````````````````````````````````````````````````````````````````````````````` [ 5.838496] e1000e: Intel(R) PRO/1000 Network Driver [ 5.838515] e1000e: Copyright(c) 1999 - 2015 Intel Corporation.
