I didn't think to get a pcap, but I'd note all switches three hops out from= =20 the thing blinking madly on all ports. Not yet having the culprit identified, we moved things yesterday so that th= e=20 Thinkpad ended up being one switch closer to the central switch in the cell= ar, and it knocked out most of the network in the house, rather than just my office.=20 I'm not sure how best to debug this. I can't have the thing loose on my=20 network, but I can construct a DMZ and let it live in that for data=20 collection. Before I dive into that, though, I'd love to get a list of data= =20 that would be maximally useful for me to collect. The system in question is a Thinkpad T420, and the NIC is an Intel 82579LM.= =20 It's running updated FreeBSD 12-RELEASE. --=20 You are receiving this mail because: You are the assignee for the bug.=
