The MMC card is very slow on vexpress, and heavy CPU activity causes this to happen.

That's just the way it is. Tixy has discussed a proposed fix with ARM, but this is definitely wishlist! I don't think it needs reporting further.

This issue can't be observed on the latest ubuntu raring image, then the status of this bug will be changed to "Fix Released".
