This line in dmesg means that your hardware saw the cable disconnect.
You should be able to see this effect by running "ethtool eth0 | grep
Link". There is nothing that Gentoo can do to cause this...it is
purely between the kernel driver and the hardware. Even "ifconfig
eth0 down" doesn't cause this.
This could be the fault of the chip in the laptop, the cable, or the
switch that you plug into. Since you already tried a different cable,
and the NIC chip isn't easily replaced, I would try to prove that the
switch is good. Assuming you have control over the switch, try
different port. Or if you don't, insert a small desktop switch
between you and the upstream one.
