Amigo da lista bom dia.
Alguém por aqui tem enfrentado problemas com o nouveau?
Comigo aconteceu algo bem estranho. Na minha estação desktop começou a aparecer a mensagem
[drm] nouveau 0000:00:0d.0: ======= misaligned reg 0x0060081D =======
[drm] nouveau 0000:00:0d.0: ======= misaligned reg 0x0060081D =======
Retirei a placa de vídeo que estava usando e deixei na on-board e a mesma mensagem surgiu. Isso ficou durante alguns dias. Hoje o Gnome não inicializa no novo padrão, usando a antiga tela informando que não tenho capacidade de vídeo.
O mais interessante é que notei no meu firewall (que não tem xwindows) também uma mensagem relativa ao nouveau.
No final do email esta o log com as informações relativas ao nouveau e abaixo os fragmentos do dmesg do desktop e do firewall que me chamaram a atenção
