4 This line in dmesg means that your hardware saw the cable disconnect.
5 You should be able to see this effect by running "ethtool eth0 | grep
6 Link". There is nothing that Gentoo can do to cause this...it is
7 purely between the kernel driver and the hardware. Even "ifconfig
8 eth0 down" doesn't cause this.

10 This could be the fault of the chip in the laptop, the cable, or the
11 switch that you plug into. Since you already tried a different cable,
12 and the NIC chip isn't easily replaced, I would try to prove that the
13 switch is good. Assuming you have control over the switch, try
14 different port. Or if you don't, insert a small desktop switch
15 between you and the upstream one.
