Hardware : ML 350 G4 Proliant. 2x Xeon 3.2 Ghz, 1 Go Ram.

I have the same problem from 2 mounth (regulary update the kernel, all src and make world)

I've server running FreeBSD, on this server I've 5 network interfaces. This server running one service : nfsd. And It's only purpose.

After reboot everything work fine, but after few days (10 - 15 days) the network interface don't work and I've many message on console like :
        bge0 watchdog timeout problems                                                                            
        fxp1 watchdog timeout problems   
I can logon on console and if I reboot everything work fine again but if I try to make up the interface (using ifconfig bge0 down; ifconfig bge0 up .... nothing work). 

Someone tell it's better to switch no-smp kernel. I make new no-smp kernel and...it's working ...during few days and crash again (and this time I can't logon on console). I've same kind of message on the console.
