In searching the list archives, I did see mentions of there being an issue = with scatter/gather with symptoms affecting ssh connections in/out going and likely other network issues. Are there sy= sctl parameters or other settings that could get around this issue? The ssh symptom (as reported by others) looks like this: debug1: Local version string SSH-2.0-OpenSSH_6.8 NetBSD_Secure_Shell-201504= 03 debug1: Remote protocol version 2.0, remote software version OpenSSH_7.2 Fr= eeBSD-20160310 debug1: match: OpenSSH_7.2 FreeBSD-20160310 pat OpenSSH* compat 0x04000000 debug1: Remote is NON-HPN aware debug1: mac 0x0, -1 -1 debug1: SSH2_MSG_KEXINIT sent Bad packet length 168430090. debug1: mac 0x0, -1 -1 ssh_dispatch_run_fatal: message authentication code incorrect
