I am not familiar to the lro and epoch code. the HyperV hn driver had couple commit since March 12. The commits are about RSC support for packets from same host. Is the NFS server VM running on the same Hyper-V host? If it is easy for your reproduce on the current build, can you try any build before March 12 to see if it is reproducible? --=20 You are receiving this mail because: You are the assignee for the bug.=
