Moin!

I saw a such issue on amd64, both 13.0-RELEASE and -CURRENT.
Both hosts have zfsd enabled, and after devd die by signal 15 all other daemons such as sshd, crond, syslogd (almost all runned daemons) stopeed by signal 15 too. At least, as it shows by system logs.

Will try to play with zfsd disabled, as suggested.
