Inicialização lenta devido a vários “[sdb] O teste WP falhou, suponha que a gravação esteja ativada”

Question

Meu laptop inicializa devagar.

Quando eu vejo dmesg, vejo lacunas relativamente grandes em [sdb] Test WP failed, assume Write Enabled , que ocorreram várias vezes ... até 18 vezes.

As grandes lacunas ocorrem no final do log - da linha 773 para a linha 840.

Como devo corrigir isso?

Você pode ter um leitor de cartão SD configurado como sdb. Seu sistema deseja configurá-lo durante a inicialização, mas não pode, pois não há cartão. Tente inserir um cartão se isso ajuda (apenas para diagnosticar, não para corrigir ...; -)
