Explicit Congestion Notification?
Perhaps it is a more generic Linux issue in that your new kernel uses
tcp_ecn whereas your old one did not.
Maybe a quick
# echo 0 > /proc/sys/net/ipv4/tcp_ecn
will get the network going again.

I have experienced a weird problem with the networking
on my sparc system.
After upgrading to:
Linux carpel 2.4.21 #1 Thu Aug 7 20:30:12 EDT 2003 sparc64 GNU/Linux
from 2.4.18, the tcp layer seems to be broken for any host outside
the local area network.
ICMP works, so I can ping www.debian.org but tcp just hangs.
All firewall policies are set to ACCEPT.
The system is an ultra 60 with a happy meal eth0 configured using
dhcp. resolv.conf and the route all seem correct. Using a different
LAN address doesn't solve the problem.
Any ideas?
