>Description:
I turned on DIAGNOSTIC on NetBSD 10.0_STABLE server to help me identify a ZFS related crash but it crashed in if_wg instead:

panic: kernel diagnostic assertion "wgp->wgp_handshake_start_time != 0" failed: file "/usr/src/sys/net/if_wg.c", line 3389
>How-To-Repeat:
Build a recent netbsd-10 kernel with "pseudo-device wg" and "options DIAGNOSTIC" and use wg for a couple of hours.
>Fix:
not known
