Como reduzir a saída muito detalhada do driver Realtek rtl8821ae no syslog

Question

Usando o Ubuntu 14.04 com o cartão Wi-fi Edimax PCI-E que usa o driver Realtek.

Ao usar meu adaptador sem fio PCI-e (rtl8821ae) no modo sem fio, o kernel está gravando informações muito detalhadas no syslog. Como posso parar esta informação spam no syslog.

Abaixo está uma amostra do que está acontecendo. Certamente há uma maneira de reduzir essa informação. Esperando que alguém possa ajudar com esse problema. Eu tentei pesquisas no Google, mas não consigo encontrar ajuda até agora. Agradecemos antecipadamente.

O upgrade do kernel do Ubuntu 14.04 para o linux-generic-lts-vivid 13.19 corrigiu o problema. Driver no kernel LTS original foi o problema.
