Solução definitiva: Substitua a Gigabyte GA-H77M-D3H por uma Asus P8H77-M
Eu atualizo para o Ubuntu 13.04 e algumas vezes aparece na tela de inicialização uma mensagem:
Disabling IRQ #16
Quando esta mensagem aparecer, devo reiniciar porque o mouse fica muito lento e não responde corretamente. Eu suponho que seja um problema de Conflito de IRQ, mas como posso resolvê-lo?

NOVIDADES:
Eu removi a ethernet externa RTL8169 para simplificar as possibilidades de erro. Sem essa placa, eu testei diferentes configurações da BIOS e o resultado é:

Notícias: Eu testei com os últimos BIOs. O erro persiste, mas menos erros aparecem no dmesg. Por exemplo, * BAD * gran_size foi desaparecido. Uma curiosidade: arquivos Firmwares na web da GIGAByte são .exe !!!! e a última imagem do BIOS é a versão beta de 10 meses de idade!
Solução definitiva: Substitua a Gigabyte GA-H77M-D3H por uma Asus P8H77-M
