The reason is missing AF_INET6 check at line 526 in fs/nfsserver/nfs_nfsdcache.c: if (so->so_proto->pr_domain->dom_family != AF_INET || so->so_proto->pr_protocol != IPPROTO_TCP) panic("nfs sent cache"); >How-To-Repeat: Mount NFSv4 using IPv6 and newnfs server. >Fix: Change the line 526-527 sys/fs/nfsserver/nfs_nfsdcache.c to: if ((so->so_proto->pr_domain->dom_family != AF_INET && so->so_proto->pr_domain->dom_family != AF_INET6) || so->so_proto->pr_protocol != IPPROTO_TCP) panic("nfs sent cache"); It works after that. >Release-Note: >Audit-Trail: >Unformatted:
