No sure if -stable is the right mailing list for this one. We recently moved our software from 11.0-p9 to 11.1-p1, but looks like there is a regression in 11.1-p1 running on HyperV (Windows/HyperV 2012 R2) where the virtual hn0 interface hangs with the following kernel messages: hn0: <Hyper-V Network Interface> on vmbus0 hn0: Ethernet address: 00:15:5d:31:21:0f hn0: link state changed to UP ... hn0: RXBUF ack retry hn0: RXBUF ack failed last message repeated 571 times It requires a restart of the HyperV VM. This is a customer production server (remote customer ~4000km away) running fairly critical monitoring software, so we needed to roll it back to 11.0-p9. We only have two customers running our software in HyperV, vs lots in VMware and a handful on physical hardware. 11.0-p9 has been very stable. Has anyone seen this problem before with 11.1 ? 11.1 is listed here https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/supported-freebsd-virtual-machines-on-hyper-v Paul. -- Paul Koch | Founder | CEO AKIPS Network Monitor | akips.com Brisbane, Australia
