Instale o driver de vídeo da AMD executando
sudo apt-get install fglrx-updates
e reinicie.
Oi estamos enfrentando falhas no kernel após 4-5 dias. Estamos usando o kernel 3.18.24 por causa da falta de drivers nos dispositivos BlackMagic (que não estão prontos para o 4.2.0) - suspeitamos que o problema não está vindo desse driver que não é o opensource.
Também estamos usando a placa gráfica externa AMD com o driver OSS radeon. Primeiro acidente foi algo sobre a placa de rede 8192 - acho que alguns DNS
Eu posso fornecer apenas uma imagem do backtrace do kernel panic (nos logs não há nada): Primeiro acidente:

Instale o driver de vídeo da AMD executando

e reinicie.
Confirmado para o Xubuntu 15.10
Meu Hardware: Asus EeePC 1201 HA
Não possui um dispositivo gráfico da AMD, mas o infame chipset INTEL GMA500. Por causa disso, nem tentei instalar um driver de vídeo da ATI. No entanto, o bug será reproduzido da seguinte forma:
Minha solução alternativa:
sudo rmmod eeepc_wmi
Depois disso, a maioria das teclas de atalho da Asus não funciona, mas a mudança de brilho da tela funciona, apesar de nenhum OSD ser exibido em um ambiente gráfico.
depois de reativar o módulo,
sudo modprobe eeepc_wmi
outros Asus Hotheys trabalham novamente, mas a mudança do brilho da tela congelará o sistema.
