this happens with 3.99.10 (my kernel, built a few minutes ago) as well 
as the 3.99.9 GENERIC.MP from NetBSD-daily (HEAD).

dmesg attached below.

the problem usually appears when transferring huge files in the LAN, but 
it starts as early as in ssh handshaking (transfer on the LAN via scp(1)).

the machine is connected to a 10/100 hub which makes no trouble to any 
of the other six connected machines/devices.

i can setup the machine to a managed switch and have a deeper look at it 
on request.

is this a known problem (at least there's no PR on this)?

thanks,

timo
