>Description:
Mar  4 04:09:57 gw kernel: nve0: device timeout (1)
Mar  4 04:10:28 gw kernel: nve0: device timeout (1)
Mar  4 04:11:34 gw kernel: nve0: device timeout (19)
Mar  4 04:12:38 gw kernel: nve0: device timeout (37)
Mar  4 04:14:31 gw kernel: nve0: device timeout (64)

the problem happens after some days running normally

no traffic goes through anymore
anyway ifconfig says "active"
ifconfig up/down does not change anything cable unplugging either

the interface was running fine on stable aprox 1 or 2 weeks before above kernel date

nve0: <NVIDIA nForce MCP7 Networking Adapter> port 0xd400-0xd407 mem 0xf6000000-0xf6000fff irq
 20 at device 5.0 on pci0
