Re: [OCLUG-Tech] Debian browser wierdness

Sebastien, this could be a problem with explicit congestion
notifications (ECN).  You can disable it like so...

echo 0 > /proc/sys/net/ipv4/tcp_ecn

(as root)

The fault is at the web server or its router, not your kernel.  The
older kernels had ECN disabled (or maybe not implemented).
