Kernel Oops ao Acessar dispositivo USB

[Maycon Maia Vitali]

Pessoal,

Estou tendo um problema extremamente chato de resolver.

ALGUMAS VEZES, quando insiro algum dispositivo USB (Pendriver, sensor etc) ele cria o dispositivo corretamente, porém ao acessá-lo (escrita ou leitura) eu tomo um Oops no Kernel e o X cai, mostrando o stack trace do kernel, quando removo o dispositivo outro erro semelhante acontece seguidamente.

Alguém já teve algum problema semelhante?

Pessoal,

Estou tendo um problema extremamente chato de resolver.

ALGUMAS VEZES, quando insiro algum dispositivo USB (Pendriver, sensor etc) ele cria o dispositivo corretamente, porém ao acessá-lo (escrita ou leitura) eu tomo um Oops no Kernel e o X cai, mostrando o stack trace do kernel, quando removo o dispositivo outro erro semelhante acontece seguidamente.

Alguém já teve algum problema semelhante?

SIM !!!

Semrpe que tento usar um modem 3G, da Claro ou Vivo, ocorre este mesmo comportamento...  Mas dando um tempo dá para volta para o X. Não lembro se ocorre espontaneamente ou se tem que usar o Crtl-Aly-F7.

O modem  até funcionava, pelo menos o da Claro,  mas de uns 40 dias para cá nem o discador consegue conectar... Mas isso é outro assunto.

Uso teclado USB, mouse USB e pendrive, com eles não ocorre o Oops, só com modens 3G USB.

Gostaria muuuito de alguma sugestão de o que tentar pois já fiz muitos mexes sem conseguir ao menos evitar o Oops...

Pessoal,

Estou tendo um problema extremamente chato de resolver.

ALGUMAS VEZES, quando insiro algum dispositivo USB (Pendriver, sensor etc) ele cria o dispositivo corretamente, porém ao acessá-lo (escrita ou leitura) eu tomo um Oops no Kernel e o X cai, mostrando o stack trace do kernel, quando removo o dispositivo outro erro semelhante acontece seguidamente.

Você usa o kernel padrão?

[Maycon Maia Vitali]

Sim. Uso o kernel padrão, e também uso teclado e mouse USB sem problema algum.

Pessoal,

Como faço para reinstalar aqueles módulos achi, ehci_hcd etc?

Ou alguém tem alguma ferramenta que faça teste de hardware?

parece que o problema é modulo ftdi_sio ou
algo relacionado ao mesmo.
se o hardware for recente, voce pode ter uma
sub-versao do hardware incompativel com os
modulos.

dar boot por 1 ou + CD LIVE e testar, pode
tirar a dúvida quanto a possivel problema
na instalação, ou mesmo versão do kernel.

Bom pessoal, a thread é antiga mais gostaria de falar que o problema aparentemente sumiu após alguma atualização do sistemas. O colega que estava com um problema semelhante poderia compartilhar se o problema foi resolvido com alguma atualização também?

Abraços a todos.

Sim !

Relato que o modem 3G da Claro Huawei E173 não está mais gerando Oops do kernel e está funcionando como deveria...

Muito bom !!
