procurando sugestões sobre como resolver um problema com meu leitor de cartão SD. Primeiro eu tentei ver se atualizar o kernel para 3.16 seria suficiente, e isso não aconteceu. Em seguida, encontrei instruções para modificar o módulo do kernel aqui: link
A instrução do exemat nesse link funcionou, mas agora estou recebendo um erro na inicialização: "LUN inválido" e "Número de alvo inválido". Eu posso inicializar a área de trabalho, e os arquivos do cartão podem ser lidos e copiados, mas estou preocupado que isso possa ter algum efeito sobre o qual não estou claro. Eu tenho uma razão para me preocupar?
Estou colando informações relevantes e, se tiver perdido alguma informação, entre em contato. Obrigado.

Faz alguns anos desde que eu vi meu último bad lun : LUN = número da unidade lógica em uma cadeia SCSI. Então, se todos os seus discos funcionam bem, provavelmente é apenas um aviso do driver (experimental!) ...
Então, o melhor que você pode fazer é definir [Ignore mode on]
