Ubuntu lento num IBM

Andre Cavalcante · 04 de Novembro de 2005, 12:24

Caríssimos, é o seguinte:
Temos 6 computadores IBM ThinkCentre P4 com 512M de RAM e HD de 40G, e instalamos o Ubuntu 5.10 em três deles. O problema é que o Ubuntu, após algum tempo aleatório fica muito lento, como se houvesse algum processo consumindo todo o tempo do processador. Entretanto, tanto o Monitor do Sistema quanto o top (ou htop) não indicam nada anormal no processador. Mesmo reiniciando o X o computador continua lento. Isto em todas as máquinas. O problema é sentido principalmente quando se deixa o computador ligado de um dia para o outro.
Instalamos em outra máquina, desta vez não é um IBM, mas uma destas montadas placa a placa. O Ubuntu roda lindamente, o que mostra que seja algum problema nos nossos IBMs. Estranho é funcionar em uma máquina não certificada (sem marca) e não funcionar no padrão do PC.
Já reinstalamos o Ubuntu e não adiantou nada.
Segue abaixo a saida do lshw e do lsmod

Alguém já teve algum problema semelhante?
O que poderia estar ocorrendo?

Pelas mensagens parece que você está utilizando EXT3 como sistema de arquivos.
Vocês tentaram alguma instalação com ReiserFS?

Andre Cavalcante · 04 de Novembro de 2005, 18:18

Tentamos instalar com ReiserFS mas o particionador ficava azul , com o cursor piscando no canto e não fazia nada. Vou tentar de novo. Você acha que pode alguma coisa relacionada ao disco? O ext3 é o formato recomendado em distros baseadas no debian, como no caso do Ubuntu.

Essa é uma possibilidade que acho estar ligada a uma incompatibilidade com alguns chipsets.

Eu tive um problema muito similar com essa nova versão só que num notebook da Toshiba, em outra máquina montada, este problema não ocorreu. Tentei de tudo descobrir o que seria a tal lentidão que não usava carga no processador mas não cheguei numa conclusão definitiva.
Desconfio de algumas coisas.
- incompatibilidade com o chipset e possivelmente com o sistema de economia de energia (acpi)
- incompatibilidade com a interface ide do disco (algum bug, por isso te perguntei sobre o sistema de arquivos)
- problemas no powernow (também economia de energia, direto no processador).
- algum aplicativo mal comportado que utiliza acesso em disco demasiado causando a lentidão.

Você pode fazer o seguinte a titulo de teste. Tenta instalar a versão 5.04 do ubuntu e observa se este problema ocorre lá também pois nesta versão não detectei nenhum tipo de problema referente a isso.

A minha suspeita referente a alguma incompatibilidade foi apliada quando vi alguns posts aqui no forum relatando lentidão nesta nova versao e outras relatando mais rapidez do sistema.
