Estou usando o Ubuntu 12.04 LTS na Intel NUC. E depois de entrar na minha conta. O sistema trava e não responde a eventos IO de teclado / mouse. Mas eu posso login remoto (Desktop Sharing) da máquina Windows. Quando eu dmesg vejo crash. Por favor, encontre os logs anexados.
Nota: Estou usando o adaptador USB para Ethernet para conectar a outra máquina.
