Por que meu Slackware 13.37 está congelado com um bug do kernel?

Question

Meu Slackware 13.37 começou a congelar de tempos em tempos. O mouse e o teclado param de funcionar, enquanto o xmms continua tocando a música. Eu colo meu syslog e espero que alguém possa ver o motivo da falha.

Answer 1

i915 é o seu driver gráfico, tente fazer downgrade ou atualização dele para várias versões. Se isso não resolver o problema, tente novamente com a versão mais recente e registre um bug com essa versão.
