Eu atualizei para o kernel linux 4.3 no Debian Jessie via backports , ie
apt-get -t jessie-backports install linux-image-686-pae
no meu laptop 32Bit com extensão de endereço físico e agora, após a inicialização, a tela permanece escura (eu uso o Gnome como fornecido pelo debian como ambiente de desktop). Em um terminal virtual ( Ctrl+Alt+F1 ), executei dmesg logs, que contém várias vezes entradas como as seguintes:

Alguém pode se relacionar ou teve problemas semelhantes? Eu sou um pouco impotente, pois não sei nada sobre problemas de hardware, kernel do Linux e assuntos relacionados.
