I've not tested with 4.0. This machine needs to be rock solid, it will be Debian stable all the way, 4.x will only get on this machine when stable is updated to that kernel.

You'll have to hope Henrique is still following this, I don't have an answer.
Just thinking out-loud here: I've got an identical server with FreeNAS installed, that's never disappeared off the network. Also I've had a server for about 5 years at home with the same on-board NIC, (different mobo), that's never locked up either, but I was able to force it to lock up with "/etc/init.d/networking restart". It seems that, at home at least, I've been fortunate so far. WRT to the FreeNAS, I have no idea how that's driving the NIC, listing the modules there doesn't show anything I recognise, and I've minimal experience with *BSD.
