Comment 9 for bug 83231

I'm having the same problem on a dmraid root partition.

I've had a look at bug #85640 about problem on crypted root partition. It seems their problem is due to the fact that /dev is not completely populated when it try to decrypt. I wonder if we don't have the same kind of problem here...

They solved it by using udevsettle. In my opinion, it would be a nicer solution than a sleep. so I'll give it a try this evening.
