Bug#861801: grub: Booting without "quiet" fails and drops to initramfs prompt.

[Mark Ter Morshuizen]

Source: grub
Version: 2.02~beta2-22+deb8u1
Severity: normal

Dear Maintainer,

   * What led up to the situation?

   Removing "quiet" from the grub command line causes booting to fail.
   The system drops to an initramfs prompt complaining that it can't
   find the UUID based boot device. Adding "quiet" to the grub kernel
   line fixes it again.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

   Editing /etc/default/grub to enable kernel messages causes the
   problem. Booting with "quiet" manually fixes it temporarily, editing
   /etc/default/grub fixes it permanently.

   * What was the outcome of this action?

   System does not boot.

   * What outcome did you expect instead?

   The system to boot with visable kernel messages.
