The messages might get dropped when the output queue is full.
Does one of the drop counters shown by "ip -s link list"
and "tc -s -d qdisc show" increase (the other counts might also
give some clues)? Otherwise please apply the attached patch
(should fix tcpdump, last patch was incomplete) and post a dump.


No visible improvement with the new patch.

Does this mean tcpdump doesn't show any packets?

ip -s link doesn't show any
dropped packets so far with any patch and I don't use traffic control
that I'm aware of. But I'm not sure what to make of "tc" output, maybe
because CONFIG_SHAPER is not set:

# tc -s -d qdisc show
RTNETLINK answers: Invalid argument
Dump terminated

Thats because you're missing CONFIG_NET_SCHED. Please enable it and
try the tc command again, without it we can't see whether the qdisc
(which is present even without CONFIG_NET_SCHED) just dropped the
packets.
