Acabei de comprar um novo laptop Dell com o Windows 8 e estou tentando instalar o Ubuntu 14.10. Eu usei o Criador de disco de inicialização com a imagem de desktop PC Intel x86 para criar uma unidade USB inicializável do Ubuntu com um formato FAT32. Eu verifiquei o md5sum do arquivo .iso e ele correspondeu ao md5sum oficial. Eu inicializei o novo PC e mostrei essas linhas de saída.

Eu reiniciei manualmente depois de esperar de 5 a 10 minutos e recriou a unidade USB. Eu reiniciei com os mesmos resultados (parando no mesmo lugar).
Acho que o erro na linha sete (kernel BUG) é a causa raiz do problema, mas posso estar errado. Existe alguma maneira de corrigir ou contornar esse bug para instalar com sucesso o Ubuntu?
Eu tentei inicializar com inicialização herdada e segura e com o UEFI ligado e desligado. O mesmo bastão funciona perfeitamente em outros computadores.
Se houver mais informações relevantes que eu possa estar deixando de fora, me avise.
