Dear reader, Today, I did upgrade FreeBSD 10.1 to 10.2 running on Hyper-V on a full pa= tched Windows Server 2012 R2 x64 version. After the update, networking does not work anymore. In /var/log/messages is this: Jan 25 21:02:01 mercurius kernel: hn0: <Synthetic Network Interface> on vmb= us0 Jan 25 21:02:01 mercurius kernel: hn0: unknown status 1073872902 received Jan 25 21:02:01 mercurius kernel: hn0: unknown status 1073872902 received Jan 25 21:02:01 mercurius kernel: hn0: hv send offload request succeeded Jan 25 21:02:01 mercurius kernel: hn0: Using defaults for TSO: 65518/35/204= 8 Jan 25 21:02:01 mercurius kernel: hn0: Ethernet address: 00:15:5d:ac:11:08 Jan 25 21:02:01 mercurius kernel: hn1: <Synthetic Network Interface> on vmb= us0 Jan 25 21:02:01 mercurius kernel: hn1: unknown status 1073872902 received Jan 25 21:02:01 mercurius kernel: hn1: unknown status 1073872902 received Jan 25 21:02:01 mercurius kernel: hn1: hv send offload request succeeded Jan 25 21:02:01 mercurius kernel: hn1: Using defaults for TSO: 65518/35/204= 8 Jan 25 21:02:01 mercurius kernel: hn1: Ethernet address: 00:15:5d:ac:11:09 Jan 25 21:02:01 mercurius kernel: hn2: <Synthetic Network Interface> on vmb= us0 Jan 25 21:02:01 mercurius kernel: hn2: unknown status 1073872902 received Jan 25 21:02:01 mercurius kernel: hn2: unknown status 1073872902 received Jan 25 21:02:01 mercurius kernel: hn2: hv send offload request succeeded Jan 25 21:02:01 mercurius kernel: hn2: Using defaults for TSO: 65518/35/204= 8 Jan 25 21:02:01 mercurius kernel: hn2: Ethernet address: 00:15:5d:ac:11:07 It worked fine with the 10.1 kernel, and when I boot this kernel, it works = again: Jan 25 22:20:02 mercurius kernel: hn0: <Synthetic Network Interface> on vmb= us0 Jan 25 22:20:02 mercurius kernel: hn0: Ethernet address: 00:15:5d:ac:11:07 Jan 25 22:20:02 mercurius kernel: hn1: <Synthetic Network Interface> on vmb= us0 Jan 25 22:20:02 mercurius kernel: hn1: Ethernet address: 00:15:5d:ac:11:08 Jan 25 22:20:02 mercurius kernel: hn2: <Synthetic Network Interface> on vmb= us0 Jan 25 22:20:02 mercurius kernel: hn2: Ethernet address: 00:15:5d:ac:11:09 So I am running a 10.2 system on a 10.1 kernel at the moment. I found nothing in /usr/src/UPDATING and not really anything on the net. So, could you tell why does this happen, and how can I solve this? Thanks for the help! With kind regards, Jac Backus
