[Bug 47367] Flash card reader only works with some SD cards

[Nicholas Allen]

Public bug reported:

I have an internal flash card reader that can read SD cards. Some cards
work without any problem but others are not recognized at all. I know
there is no hardware problem because if I boot into Windows they can all
be read and the cards work in other laptops too.

When I insert a card that cannot be read I get the following messages in
/var/log/kern.log:
