So STP is enabled, but it doesn't count, the same problem if it's off.
Dropped packets number increasing continuosly.

That same happens if the system is lucid and backported kernel is running (maverick or above).

On this LAN there is multiple system with similar configuration and all produce this error.
On another network it works with no problem, but there is no more similar setup.
