Unfortunately, the network chip is still not working and I updated the PR (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=197535) with the last tests. It seems that received packets are not transferred to mbuf or they are transferred, but later, after the mbuf is already freed; moreover, the ring entries are written without looping, overwriting and messing up the whole kernel memory. It looks like a DMA issues, but Apparently it seems a hardware error, but using a Linux distro, it works :( Has someone maybe any other ideas? In the meanwhile I'll get another board with the same chip :O Best regards, Luca On Tue, Feb 17, 2015 at 7:31 PM, O.
