Comment 0 for bug 1073108

When a RAID1 system is degraded (e.g. unplug /dev/sdb, leaving obnly /dev/sda), grub-pc properly enters prompt but system is reset as soon as one attemps to boot OR one enters the command-line and issue the 'ls' command.

This bug is known (and presumably fixed) to Debian:
Shortly put: adding the 'GRUB_TERMINAL=console' to '/etc/default/grub' (and executing 'update-grub' afterwards) allows to circumvent the issue (verified on Ubuntu/Quantal 12.10).

I believe this bug is critical because it shows up only when a disk fails but remains latent on a healthy system.
