De acordo com os testes que eu fiz conseguir resolver digitando os comandos que você me passou, o IOMMU está desabilitado, deixei como está por enquanto.
Desculpe mas fiz esses procedimentos no Debian 8 que também apresentou o mesmo problema.
<<< Você não sabe o quanto fico feliz em ter resolvido com a sua ajuda, muito obrigado mesmo Deus te abençoe.
Graças a Deus e a você resolvir o problema qua me atormentava há mais de um mês
Kernel Debian: Linux debian 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 GNU/Linux
1) Qual a versão do Ubuntu? (ambiente, sabor, arquitetura, kernel?)
O meu teclado é USB e não conseguir ver a versão do kernel
Ubuntu 14.04.1
Ambiente: é o Unity
2) Qual a versão do kernel no Fedora e no qual o problema não existe?
Faça uname -a no Fedora e no Ubuntu e informe aqui.
Linux localhost 3.17.4-301.fc21.x86_64 #1 SMP Thu Nov 27 19:09:10 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
O problema so nao existe no Fedora 20
No Debian e no Ubuntu o problema sao os mesmos mencionados
3) Em que circunstância e mais exatamente onde aparecer esse erro mencionado?
O erro aparece depois de tela de boot(depois da contagem regressiva na inicia a tela preta)
4) Geralmente há um código de erro após essa mensagem que você colocou aqui.
Se existe, qual é ele?

Por exemplo: error -110 ou error -71 ou error -84 e assim vai.
5) Consertou fazendo o quê no Win?
Descreva a solução lá encontrada e ao que se referia, porque possivelmente é o mesmo caminho no Linux, apenas que usando outras ferramentas, mas a essência da questão deve ser a mesma, daí porque explicar isso pode ajudar.
Gerenciador de Dispositivos>>Controladores USB>>Cliquei com o botão direito em USB Root Hub>>Desativar
6) Verifique se no BIOS há a opção IOMMU e se existir altere para Enabled, caso já não esteja.
IOMMU está desabilitado
