Test_ConnectPeers fails every few weeks on the Linux runner with a bare "waiting for peer handshake timeout after 30s". The failing logs show both kernel devices up and both peers configured within a second, then nothing for 30 s, which is six retries of the 5 s handshake retransmit and so a condition that lasted the whole window rather than a race. The failure cannot be reproduced locally and the log cannot tell whether initiations were sent, whether they arrived, or whether only one direction worked. On timeout the test now prints each device's view of its peer, the endpoint, the byte counters and the last handshake, so the next failure says which of those it is. The comment also states that the peers are kernel devices on the runner and that the first initiation of each side is always lost to the other side not knowing the peer yet.
