kernel do Linux 3.3 regressão de energia

Question

Estou usando o Fedora 16 na minha DELL n4110. Eu recentemente atualizei o kernel de 3.2 para 3.3. Em contradição com a alegação oficial, meu sistema ainda consome bateria como o inferno. Ele fornece apenas 1:30 a 2 horas de backup sob estresse normal como antes, enquanto o Windows fornece 3hrs / + de backup sob estresse semelhante.

Abaixo estão algumas capturas de tela de powertop , estatísticas sobre os serviços em execução na minha caixa e algumas linhas do grub.cfg. Espero que isso ajude.

Isso é normal? Ainda existem problemas com consumo de energia em 3,3?

Is there any way to report this problem to the official kernel group???

    

Answer 1

O problema desapareceu com novas versões do kernel do linux :). Eu não vi regressão de poder desde o ubuntu 14.

    

Answer 2

De esta página , que também deve estar na fonte do kernel usado para compilar 3.3 ...
