O drive USB3 conectado ao PC faz o computador travar “welcome to grub”

Question

Eu tenho um disco rígido Seagate 2TB USB2, ext4 formatado. Se eu conectá-lo ao meu sistema e arrancar, o PC fica preso em "welcome to grub". Se eu reiniciar sem a unidade USB conectada, o sistema inicializa normalmente. Eu posso então ligar o drive e usá-lo.

Estou usando Debian GNU/Linux jessie/sid atualizado para o mais recente.
O Ubuntu livecds / usbs inicializa bem.

lsusb (do drive externo):

Bus 001 Device 006: ID 0bc2:3332 Seagate RSS LLC Expansion

versão do grub-pc: 2.00-14

A placa-mãe tem apenas portas USB2 (Intel H55TC) O BIOS está atualizado (tanto o firmware antigo quanto o novo experimentaram o mesmo problema).

O que poderia estar causando isso?
(especulações testáveis são bem-vindas, porque fiquei sem ideias).

Nota: Antes de encontrar o drive USB, eu simplesmente carregava cerca de 10 vezes e, eventualmente, ele inicializaria normalmente.

Aqui está meu grub.cfg

Answer 1

ordem de inicialização

Parece que a ordem de inicialização do sistema está configurada para que o sistema tente inicializar ou acessar a unidade USB. Eu iria verificar novamente no BIOS do sistema para se certificar de que o seguinte é verdade:

1. A ordem de inicialização das unidades é tal que qualquer unidade USB deve estar inativa na parte inferior da lista.

tente um computador diferente?

Se possível, confirmo que não é um problema de BIOS / hardware com seu computador paritlear & Combinação USB testando a unidade sendo conectada enquanto outro computador é inicializado com ela.

Problema com syslinux + BIOS + ext4

Me deparei com este tópico intitulado: [Resolvido] Problemas ao inicializar a partir da pen USB no ArchLinux fóruns. O comentário # 8 no tópico menciona um problema com certos BIOS 'não sendo capazes de inicializar drives particionados ext4.

trecho

According to the syslinux wiki entry:

While an ext4 formatted usb drive may boot on a more recent computer, some computers may hang if the boot partition containing the kernel and initrd are not on a fat16 partition

    

Answer 2

Eu sugiro verificar a tabela de partições do MBR, para ver se você tem algum problema no mapeamento da unidade física. Existem poucos sites e ferramentas, onde você pode simplesmente colar o conteúdo do seu mbr, e eles irão analisá-lo para você. Além disso, verifique se o seu USB não é inicializável (execute fdisk /dev/sdX , pressione p e verifique se nenhuma partição tem o sinalizador de inicialização ativado)

Para obter o conteúdo do mbr, execute o seguinte comando: sudo dd if=/dev/sda of=mbr.bin bs=512 count=1 conv=notrunc Em seguida, emita hexdump [-C] mbr.bin para ver o código mbr no formato legível por geek: D

Agora é hora de fazer uma pesquisa ....

A partir de sua descrição, parece-me que há uma boa possibilidade de que o problema esteja presente.
