Comment 3 for bug 927540

I think blacklist device maching is expanded as a regex and not as a glob, thus the * will not provide a match. Can you try the following change.

Replace:

 device {
                vendor "DELL*"
                product "PERC*"
        }

With:

       device {
               vendor DELL.*
               product PERC.*
       }

Also if you could paste the output from

$ sudo udisks --dump

It would help debug this issue, I am not on the Ubuntu team but I am trying to track down an issue that may be related to this.
