O problema foi com o segundo disco (SDB). Quando mudei a porta SATA, o problema desapareceu.

Eu tenho problema com a inicialização do Ubuntu depois de mudar o gabinete do computador e remover uma placa de rede e um controlador PCI ATA.
Antes disso, começou em alguns segundos:
Feb 1 09:02:20 mkskomp systemd[1]: Startup finished in 3.442s (kernel) + 11.089s (userspace) = 14.532s.
e agora leva quase 5 vezes mais tempo, mais de um minuto:
Feb 5 21:55:19 mkskomp systemd[1]: Startup finished in 58.857s (kernel) + 12.129s (userspace) = 1min 10.986s.
Em syslog não encontrei problemas. Como e onde posso encontrar o que há de errado?

Encontrei o comando dmesg com shows o que acontece quando o sistema inicia. O que significa isso?
