Explicação
Eu acabei de criar um novo computador. Aqui estão as especificações:
Placa-mãe: Gigabyte 990FXA-UD3
CPU: AMD FX 8350
SSD: SAMSUNG 840 Pro Series MZ-7PD256BW
Inicialmente eu tentei instalar o Linux Mint 15 com o XFCE de um Live DVD. O DVD ao vivo carregado, mas meu teclado e mouse não foram detectados ou montados, então não consegui instalá-lo. Depois de algum googling eu descobri que algumas das minhas configurações da BIOS provavelmente estavam causando o problema. Eu habilitei a pilha de rede e o controlador IOMMU (descrito aqui e aqui ) e, em seguida, os dispositivos usb começaram a funcionar e eu consegui instalar o Ubuntu 12.04.3 LTS. Mas eu realmente queria o Mint 15 com o XFCE, então eu instalei isso de novo e funcionou dessa vez! Mas então percebi que "não consegui" obter uma conexão de rede. Então eu reinstalei o Ubuntu novamente. Depois de instalar o Ubuntu, percebi que, por algum motivo, o DHCP automático não estava funcionando. Eu mudei para uma configuração manual, e depois de reiniciar o computador (não tenho certeza porque eu tive que reiniciar para obter a configuração para trabalhar) eu tinha conectividade de rede. Bem geez, eu ainda queria Mint, então eu reinstalei novamente!
Longa história curta - agora tenho o Mint 15 com o XFCE em funcionamento. Mas ainda não é perfeito. O tempo de inicialização leva uma eternidade e não há nenhuma indicação de que o computador está inicializando diferente da cor do LED no meu monitor. A tela está preta, sem qualquer informação gráfica indicando que o sistema operacional está carregando. Depois de esperar alguns minutos (eu não tenho cronometrado, mas acho que é cerca de 4 ou 5 minutos) finalmente recebo a tela de login. Mas quando tento usar o teclado ou mouse USB, eles ainda não funcionam. Eu sei que isso parece confuso porque eu disse que tudo está funcionando. Bem, o problema é que eu tenho que esperar em algum lugar entre 1 a 2 minutos antes que o teclado e o mouse funcionem. Eu posso viver com isso, mas parece que algo ainda não está funcionando direito.
Eu obtenho os mesmos resultados com o Mint 15 e o Ubuntu 12.04.3 LTS.
Assegurei que a placa-mãe tenha o BIOS mais recente instalado. Tentei atualizar os drivers para a LAN, Realtek 8111E (o site diz" driver LINUX para kernel 3.xe 2.6.xe 2.4.x "), mas quando descompartilho r8168-8.037.00. tar.bz2 o arquivo README declara "Árvore de fontes do Kernel (kernel Linux 2.6.xe 2.4.x) suportado" então eu não o instalei porque estou rodando:

Para ser claro, a LAN é um sucesso e um fracasso. Às vezes funciona (com configuração manual, não com DHCP automático) depois de iniciar o computador, e às vezes não. Os dispositivos USB funcionarão depois de esperar cerca de 2 minutos após o aparecimento da tela de login. Mas se os dispositivos USB e a LAN estão funcionando depois de uma inicialização do sistema, então eles parecem funcionar bem ... até a próxima vez que o sistema for inicializado novamente. É só errar.
Pergunta
Como pode ser visto no arquivo de log, ainda estou tendo problemas com os dispositivos USB e LAN. Como posso resolver esses problemas? Talvez algumas outras configurações da BIOS, outros drivers, ou talvez enviar um bug em algum lugar?
Obrigado.
EDITAR
Eu usei um cronômetro para saber os horários de inicialização do mouse / boot.
Boot time: 1:53.50
Mouse time: 1:22.16
Total time: 3:15.66
Isso significa que, desde o momento em que eu pressionei o botão liga / desliga, até a tela de login demorou 1:53. Em seguida, levou um 1:22 adicional antes que o mouse e o teclado estivessem operacionais (com suporte a usb 1.0 "ohci_hcd", em vez de suporte a usb 2.0 "ehci-pci"). O tempo total antes que eu pudesse entrar na máquina era 3:15.
1:53 é uma quantidade normal de tempo para o sistema operacional inicializar devido ao hardware especificado?
Tente desativar o suporte do IOMMU no BIOS. Eu tenho o mesmo sistema e estou apenas começando a configurá-lo. Com o IOMMU ativado, vejo os mesmos erros IO_PAGE_FAULT device:01:00.0 ;
com ele desativado, esses erros desapareceram, assim como erros relacionados de xhci_hcd (USB 3.0).
