A hallway conversation here at UDS with one of the kernel guys brought up the suggestion that maybe this was related to QoS. A look at the trace shows that, indeed, the packet that fails to be sent is the first one that uses DSCP class selector 5 instead of 1 or 0. Since no other traffic that runs on my laptop uses DSCP hints that I know if, this is likely to be the culprit.
