Estou tendo problemas com meu modem 3g da claro, que as vezes ele desaparece. Não é mais reconhecido. Então fui dar uma olhada nos logs do sistema e eis que encontro somente isso, no syslog:

Se eu ficar muito tempo com o leitor de logs, a janela trava, o processamento fica em 100% o tempo todo e tenho que fizanilzar o processo pra voltar ao normal.
Alguém sabe me explicar o que ocorre?
