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?

;2328681']Parece que estás com problemas no disco/controlador ide.

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.

;2328681']Não podes testar com outro disco?
Pelo menos para já não tenho essa hipótese.

Não descobri foi uma solução clara. Apenas sugestões.
Eu também não tenho nenhuma solução, apenas sugestões.

Estas linhas deixam-me intrigado:

Dec 19 11:27:29 contact-mobile kernel: [ 959.620000] ata1.00: configured for UDMA/33

e

DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4 udma5
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.
