Tarjeta Sundance Gigabit se congela luego de un momento

Hace algunos dias adquiri esta tarjeta:

02:06.0 Ethernet controller: Sundance Technology Inc / IC Plus Corp IP1000 Family Gigabit Ethernet (rev 41)
        Subsystem: Sundance Technology Inc / IC Plus Corp IP1000 Family Gigabit Ethernet
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-

        Kernel driver in use: Sundance Technology IPG Triple-Speed Ethernet

La tarjeta funciona muy bien al navegar pero cuando trato de pasar informacion "pesada" de una maquina a otra se congela y debo detener el servicio y volverlo a iniciar para que funcione de nuevo.

Cuando eso sucede aparece esto en dmesg:

Busque en google sobre "sundance time out" y al parecer es un bug viejo con esta marca de tarjeta, unos foros recomendaban activar y desactivar ciertas opciones con ethtool pero no me funciono sigue congelandose.

Por el momento se me hace imposible cambiar la tarjeta asi que debo encontrar la forma de hacerla funcionar :)

Gracias.
