assertion (cnt <= tp->packets_out) failed

[John Bäckstrand <sandos@home.se>]

I get

KERNEL: assertion (cnt <= tp->packets_out) failed at 
net/ipv4/tcp_input.c (1476)

with 2.6.13-rc5, also with a small netpoll patch that shouldnt affect 
these things. (Topic: "lockups with netconsole on e1000 on media 
insertion").

I have a decent amount of dropped/overruns:
