O Ubuntu trava com a tela em branco

Question

Eu instalei o Ubuntu Linux 16.04 de 32 bits (kernel 4.4.0-53-genérico). Eu tenho problema estranho depois de correr por algumas horas. O sistema trava com tela preta, e NADA funciona (como o sistema está desligado)! Eu então iniciei manualmente o sistema, e verifiquei o arquivo / var / log / syslog, e existem várias linhas, como abaixo, antes do sistema travar.

Nota: o sistema NÃO possui conexão com a internet.

É normal ter essas mensagens? Não tenho certeza se o servidor NTP está travando o sistema. Eu preciso de sua ajuda pessoal!

Answer 1

Ok. Você tem um CPU Bay-Trail que é conhecido por causar problemas com o Ubuntu em relação aos estados de suspensão.

Faça o seguinte:

sudo -H gedit /etc/default/grub

Encontre a linha GRUB_CMDLINE_LINUX_DEFAULT e adicione o parâmetro intel_idle.max_cstate=1 .

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1"

Depois de fazer isso, feche o Gedit e execute o comando:

sudo update-grub

E reinicie.

Esta é uma correção muito suja . Por favor, mantenha-se atualizado com os kernels mais recentes, pois este bug provavelmente será corrigido no futuro.
