Yes, by massively downloading things :-) But I have no real recipe to

Looks like you are in fact interested in:
grep WARNING: /var/log/kern.log | cut -c 40- | sort -u

net/ipv4/tcp_input.c:1771 tcp_enter_frto+0x267/0x270()
net/ipv4/tcp_input.c:2173 tcp_mark_head_lost+0x11d/0x150()
net/ipv4/tcp_input.c:2532 tcp_ack+0x1a6f/0x1d60()
net/ipv4/tcp_input.c:3067 tcp_ack+0x1d2b/0x1d60()
