Estou executando o 14.04 e recebi o seguinte erro ao fazer login em uma sessão tty depois de digitar minha senha, mas antes do prompt de comando aparecer:
[198877.466429] systemd-udevd[25302]: timeout 'udisks-part-id /dev/sdb'
[198878.467543] systemd-udevd[25302]: timeout: killing 'udisk-part-id /dev/sdb' [20816]
[198878.581606] systemd-udevd[25302]: 'udisks-part-id /dev/sdb' [20816] terminated by signal 9 (Killed)
A máquina é um laptop com um disco rígido. Eu procurei por um comando para mostrar-me o que sdb ainda era e alguém entied ls -l /dev/disk/by-id então eu corri isso e aqui está a linha que mencionou sdb:
lrwxrwxrwx 1 root root 9 Jul 18 03:07 usb-Generic-_Multi-Card_20071114173400000-0:0 -> ../../sdb
O que o erro significa? Meu melhor palpite é algo está errado com o cartão usb e / ou o driver para isso? Supondo que seja o caso, como obtenho informações suficientes sobre o cartão para descobrir se há um novo driver ou algo assim?
Edit: Quando eu disse "tty session" eu quis dizer + Alt + F1 e logado dessa maneira, (eu fiz isso para matar um programa que estava tornando a minha interface gráfica inutilmente lenta).
O único cartão MMC que foi conectado no momento em que o erro ocorreu é incorporado ao laptop. Também não havia cartão inserido.
Não há menção de sbd em /etc/fstab/ , apenas algumas coisas sobre partições em sda.
Eu olhei em /etc/udev/rules.d/ e te apenas .rules arquivos que foram 70-persistent-cd.rules e 70-persistent-net.rules
Como mencionado anteriormente, o cartão MMC é integrado, portanto, não o removi. Eu corri sudo udevadm test --action=add /sys/class/block/sdb de qualquer maneira e recebi esta saída:

Olhando através de /var/log/syslog , vejo linhas como as que se seguem aparecendo aproximadamente uma vez por minuto:

Eu tentei comentar a linha 36 de /lib/udev/rules.d/60-persistent-storage.rules e reiniciar e essas linhas ainda estão aparecendo e a saída de sudo udevadm test --action=add /sys/class/block/sdb parece a mesma, incluindo a linha que diz error: /dev/sdb: No medium found
O erro de tempo limite original não apareceu desde então (antes ou depois que eu comentei a linha 36.)
