Bug#407735: 2.6.18-3-686 tcp_window_scaling serious problem
/proc/sys/net/ipv4/tcp_window_scaling is set to "1" be default in this
kernel. But there is a serious problem with this which causes severe
connection problems for some connections. The user will experience this
as sites that fail to load, or begin to load then abruptly stop and just
hang while loading.
This is fixed with:
echo "0" > /proc/sys/net/ipv4/tcp_window_scaling
I thought that this problem no longer existed as of 2.6.18 kernels, but
I can confirm this is happening again with this fresh debian
linux-image-2.6.18-3-686 kernel in unstable.
