TCP/IP just died. Please Help

Hi,
I was emerging the new KDE yesterday and when I checked out the download process I realized that it was not going forward. I tried to ping some hosts or open some sites, but nothing worked.
My machine is dual-boot, so I booted windows to see if my ISP had a problem. I went online and everything worked just fine!
ifconfig results with 2 ips and a ppp0 profile, kmyfirewall and squid are shut down, but nothing works!
Can you please help me?

Please post the following data:
ifconfig
route
cat /etc/resolv.conf

are you on dialup? (I assume so since you mention ppp)

Didn't work. I tried to ping but I got no reply...
What could have been wrong?

try to ping your default gateway.

I did but I got no reply from me. Then I called a friend and told him to ping my IP but he got no reply as well.
I traced some hosts but when it tries to reach the IP that is the next after mine, it times out.

i really do not understand WHY this is happening but a friend had a similiar (if not the same) problem.

He would get on-line normally , then after a while for no obvious reason the ppp connection would stop working (not terminate. Just stop Receiving/transmitting)

The problem seems to have been in the default Gentoo kernel (some patch combined with hardware peculiarity maybe?) . A vanilla kernel solved this.
