Comment 77 for bug 872220

I just made a full update on a 180 days old 12.04.2 system. Everything was fine before, but on reboot I'm dropped into this rescue shell, because /dev/sdc1 is detected as belonging to a degraded raid.

However, the raid is not degraded! cat /proc/mdstat shows it as healty (keyboard is working), and after I type exit boot continues normally.

cat /proc/mdstat
