Freeze de portátil ACER em Ubuntu

Discussão em 'Novidades GNU/Linux & *nix World' iniciada por joaomiguelsa, 19 de Dezembro de 2007. (Respostas: 4; Visualizações: 1317)

  1. Tenho instalado o Ubuntu 7.10 num portátil Acer 5601AWLMI.
    Algumas vezes, sem razão aparente, o sistema congela. Algumas vezes recupera, outras não.
    Em Windows também acontece este tipo de freezes (pára tudo durante 5 a 10 segundos) mas o sistema recupera sempre.

    Tenho as seguintes mensagens nos logs que penso estarem relacionadas com o problema.
    Alguma dica?

    Parece que estás com problemas no disco/controlador ide.

    Não podes testar com outro disco?
     
  4. Talvez. Depois de alguma pesquisa vi que é um problema que acontece a mais gente. Acontece muito em portáteis Acer (vários modelos) mas também noutras marcas, e com discos distintos. Não descobri foi uma solução clara. Apenas sugestões.

    Para já, matar o processo hald-addon-storage parece ter resolvido o problema.
    Vou fazer mais testes durante algum tempo e esperar que seja mesmo isso.

    Pelo menos para já não tenho essa hipótese.

    Eu também não tenho nenhuma solução, apenas sugestões.

    Estas linhas deixam-me intrigado:
    e
    A mim também me cheira a problemas no disco/controlador.
    Ou investigas mais (actualiza a BIOS, experimenta com outro Kernel, experimenta um LiveCD, etc) ou, se está na garantia, manda-o de volta.
