Erros de DMA no roteador OpenWrt

Question

Eu tenho um roteador WRT160NL com OpenWrt Backfire (10.03.1, r29592) e há um HDD 3,5 "WD Green de 1,5 TB conectado a ele. Nos últimos tempos, se eu ler os logs nele com" logread "Eu posso ver estas mensagens:

Quais são essas mensagens? Há um sinal de um problema futuro? Como lidar com eles?

    

Answer 1

ath would be your wireless card (or at least one of them). Probably a bug in the driver for it. – derobert Dec 13 '12 at 21:52

Portanto, a solução é aguardar o firmware atualizado.
