O kernel é suspenso muito rapidamente, após o reinício continuar, suspender tarefas

29/06/2019 Atualização

Da resposta excluída abaixo (o pôster não tinha pontos de reputação suficientes para postar um comentário), um relatório de bug foi arquivado no Kernel.org Bugzilla :

• Bug 203791 - s2idle está acontecendo antes que os processos do espaço do usuário sejam congelados

Outro relatório de bug foi arquivado no Launchpad :

• Drenagem da bateria durante o sono. Sistema suspenso antes do kernel suspender todas as tarefas

21/10/2018 Atualização

O problema ainda está aqui e não importa a quantidade de pesquisas que eu fiz (principalmente a repetição de pesquisas anteriores) uma solução não esteja mais próxima. Outro usuário relatou o mesmo problema hoje: o modo de suspensão drena a bateria muito rápido

Em poucas palavras, você pode ver meu journalctl -xelog:

Observe como o sistema é suspenso em 24 de fevereiro às 23:30 e depois retomado em 25 de fevereiro às 7:40. Ao reiniciar, o sistema imediatamente entra em "suspensão" e depois "acorda".

fundo

NOTA: No Ubuntu 16.04, as configurações de energia para fechar a tampa estão definidas como "Suspender" para a bateria e Conectado.

Dentro /etc/systemd/logind.confdos padrões de "ignorar" foram alterados para HandleLidSwitch=suspende HandleLidSwitchDocked=suspend. O motivo pelo qual uma TV externa HDMI está conectada e se alguma dessas opções (ou configurações de energia do Ubuntu) estiver definida como "ignorar" ou "não fazer nada", o sistema continuará funcionando quando a tampa estiver fechada, mas a TV ficará em branco. No Ubuntu 14.04 (sem systemd), a suspensão quando a tampa fechada funcionava como esperado.

Houve muitos ajustes históricos de acpi-events, pm-utils, gnome - ??? e possivelmente dbus - ???. Também experimentando vários métodos de suspensão de congelamento e memória.

Sinceramente, não consigo me lembrar de todas as coisas diferentes tentadas, mas parece que procurei tudo sob o sol.

Conteúdo relevante de / var / log / syslog

Olhando às /var/log/syslog5:05 da manhã, o sistema foi suspenso (pelo systemd?). Às 16h46 (16h46), o systemd foi reiniciado, mas o kernel colocou o laptop em suspensão e a ativação imediata. Existem muitas mensagens estranhas, como " a CPU pai não deve estar em suspensão ".

Minha preocupação é que outras coisas estejam começando a se romper seis meses depois que essa pergunta foi publicada originalmente em outubro de 2016. Por exemplo, a Ethernet não está se reconectando ao acordar da suspensão e o wifi assume o controle. Eu rebaixei o driver r8169 para r8168, mas isso não ajudou em nada. Eu configurei a reinicialização da rede, mas isso não ajudou muito, às vezes o DNS se perde.

Aqui é relevante /var/log/syslog:

Isso é normal? (Observe que o fechamento da tampa faz a mesma coisa, exceto que o systemd suspende mais rapidamente e executa menos tarefas).

Depois de revisar todas as informações que posso encontrar, cheguei à conclusão de que você é afetado por esse bug do kernel. que afetou vários sistemas, incluindo Asus, Dell, HP, Lenovo, etc. Este bug que será marcado para expirar em 47 dias se não ocorrer mais nenhuma atividade, é extremamente quente, pontuando 412 na pontuação de calor do bug e relatado como afetando 86 pessoas neste momento. Eu recomendo que você assine e forneça qualquer informação relacionada ao kernel que possa ajudar a esclarecer o problema, para que ele permaneça aberto e os desenvolvedores possam esmagá-lo.

Uma solução provável é atualizar / reverter para o kernel 4.4.8, conforme observado aqui e confirmado aqui e aqui.

Foi solicitado trabalho para reverter a divisão do kernel, mas o bug está atualmente expirado, portanto parece que os desenvolvedores não receberam toda a ajuda necessária para determinar a causa raiz desse comportamento. Quase como posso ver ao ler o relatório de erros, esse problema apareceu no kernel 4.4.0, foi resolvido no 4.4.8 e depois reapareceu em torno do 4.5.2, mas não pretendo ter certeza.

Outra solução possível para atualização do kernel foi relatada aqui, embora eu não tenha encontrado confirmação sobre isso.

Se você estiver usando um kernel do repositório, pode ser útil iniciar ubuntu-bug linuxo terminal a fim de criar um novo relatório de erro, fornecendo informações específicas sobre seu kernel / problema.

Você também pode excluir a execução fora de ordem como culpada. Você deve conseguir isso desativando todos, exceto CPU0, como:

for x in /sys/devices/system/cpu/cpu*/online; do
  echo 0 >"$x"
done

Você também pode encontrar essas informações úteis para rastrear a causa raiz desse problema.

Este é o problema específico que aparece no dmesg:

PM: Preparing system for sleep (mem)
[...]
PM: Suspending system (mem)

Inicialmente tente fazer:

sudo -H gedit /etc/default/grub

e defina a linha:

GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor"

Outros parâmetros que existiam anteriormente nesta linha podem permanecer inalterados, ou seja, apenas adicionar isso às vezes é indicado.

Para efetivar as alterações, execute:

sudo update-grub

Além disso, há o relatório de um problema com apt-daily.service, que é o serviço de atualização executado na inicialização, o que torna tudo em execução indefinidamente, incapaz de concluir.

Tente desativar o serviço:

sudo apt-systemctl disable daily.service # disable run when system boot

Outra solução alternativa que funcionou razoavelmente para mim:

sudo -H gedit /etc/systemd/system.conf

Altere as seguintes linhas, descomentando e configurando para um valor que ainda permita o sistema de carregamento:

# DefaultTimeoutStartSec = 90s
DefaultTimeoutStartSec = 10s
# DefaultTimeoutStopSec = 90s
DefaultTimeoutStopSec = 10s

Observe o dmesg se o ajuste não gerar falha na carga e, se apropriado, ajuste o valor.

Em relação a esses comentários:

"... O kernel suspende parcialmente e desliga o sistema, mas, após a conclusão, a suspensão é suspensa com ativação imediata (nenhum problema visível além do log)"

e

"Exatamente o mesmo cenário com o 4.4.8 - Systemd suspende o sistema e, após a retomada, o Kernel imediatamente dorme e acorda. Ninguém saberia que isso está acontecendo a menos que eles examinem os logs que eu publiquei acima."

Este não é um problema real e é puramente uma conseqüência de quando a saída do console está sendo suspensa e mais tarde retomada, mas é certamente irritante ver a saída em buffer produzida durante a suspensão realmente sair durante o resumo.

Para fins de depuração, a suspensão do console pode ser desativada:

# echo N > /sys/module/printk/parameters/console_suspend
# cat /sys/module/printk/parameters/console_suspend
N

Em seguida, ative a suspensão. Por exemplo, por:

# echo mem > /sys/power/state

Você deverá ver toda a saída do console relacionada à suspensão antes de retomar exatamente como seria de esperar.
