Ubuntu 16.04 laptop pendurado, requer powercycle

3
Estou vendo uma situação estranha em que meu novo laptop Dell Inspiron rodando Ubuntu 16.04 está imprevisível, e eu não consigo descobrir o porquê. Eu não observei nenhum comportamento consistente que cause isso. O que acontece é que o sistema de janelas (usando o Gnome) congela, sem ação do mouse, sem resposta do teclado, não pode cair para shell, etc ... então eu não tenho escolha a não ser fazer um powercycle rígido para trazê-lo de volta.

O único tipo de consistência que observei até agora é que isso sempre acontece quando a tela é bloqueada e eu movo o mouse, ou logo (< 30 segundos) depois de desbloquear a tela.

Quando eu olho através do syslog para possíveis problemas, às vezes eu vejo avisos, mas esses avisos também ocorrem quando a máquina NÃO está, então, travando. Veja abaixo a seção do meu syslog para a hora imediatamente anterior à data mais recente em que isso aconteceu. No entanto, esta seção do log é antes de eu realmente desbloquear a tela e encontrar o comportamento de enforcamento. No momento do problema real, não há nada nos registros.

Eu sou um administrador de sistema experiente, mas novato em rodar o Ubuntu em um laptop, e esse problema está frustrando minhas tentativas de descobrir o que está errado.

Espero que alguém possa me ajudar a descobrir o que está errado.

Isso é muito provável problema de hardware.

Eu tive problemas semelhantes duas vezes com o novo hardware, uma vez com a nova placa-mãe e uma vez com o novo laptop. Quando você compra um novo hardware, você espera que ele voe, e quando ele começa a congelar - após a quarta ou quinta reinicialização, você pode estar pronto para jogá-lo pela janela. :)

O problema da placa-mãe foi resolvido com o novo firmware do BIOS, o problema do laptop foi resolvido em serviço com a alteração da memória defeituosa.

Se você tiver tempo e energia, e partição sobressalente no disco rígido (ou unidade externa sobressalente), você pode tentar instalar o Windows, como o problema pode estar em drivers, não precisa ser hardware com defeito.

Se o Windows estiver funcionando OK após dois ou três dias, você pode tentar desabilitar o hardware da BIOS que pode ser desabilitado (como placa gráfica) e tentar usar outra versão do kernel (mais recente ou anterior) ou desabilitar alguns drivers.

Estou ciente de que essas tarefas são complicadas, mas deduzir / depurar problemas de hardware é tarefa de usuários ou profissionais experientes.

Edit: Os laptops recentes da Dell são bastante amigáveis ao Linux (eles até tinham séries de XPS ou Inspirons rotulados como Linux dentro ou algo parecido), então kernel e & distribuição (Ubuntu 1604 foi publicado no mês passado) e instalação nova deve funcionar sem problemas. Eu sei que isso não é informação que você está feliz em ler, mas, por improvável que possa parecer (novo hardware defeituoso), é a possibilidade que não deve ser descartada sem pensar.

Eu escrevo isso para não assustá-lo, mas para acelerar a resolução do seu problema, pois lembro bem como me senti miseravelmente quando estava em situação semelhante.
