Eu configurei aqui um FreeBSD 11.1 32 bits em um PC antigo, um Asus eeePC 900 para testes.
A máquina funciona muito bem, exceto que ela trava no momento do desligamento, seja usando shutdown -r ou halt. Curiosamente, se eu pressionar teclas aleatórias, isso continua, então eu suspeito que é uma questão de falta de entropia.
Ao desligar, diz:
Stopping devd
Writing entropy file: .
Writing early boot: .
Terminated
. Aug 6 16:08:55 xxxxx syslogd: exiting on signal 15
Muitas vezes, pára aqui, por vezes, depois de alguns segundos, continua. Muitas vezes tenho que pressionar o turno aqui.
Em seguida, ele continua e exibe:
Waiting (max 60 seconds) for system process vnlru to stop... done
Waiting (max 60 seconds) for system process bufdaemon to stop...
(e trava aqui para sempre, a menos que eu pressione uma tecla). Então também vai em
Waiting (max 60 seconds) for system process syncer to stop...
Syncing disks, vnodes remaining... 3 1
Eu também bloqueia aqui com frequência ... quando pressiono as teclas, ele continua e finaliza a reinicialização.
(Sobre as pausas, eu já deixei mais de 5 a 10 minutos aguardando essa pausa ...)
Eu já instalei hs-entropy sem alterações aparentes. (está fazendo alguma coisa?) o que posso fazer mais?
A máquina em si não é terrivelmente carregada; está rodando o Apache, duas placas wifi para um teste de roteamento, ipfw, apache, hostapd, unbound, dnsmasq, ntpd, sshd.
