In fact, the warning is going to be removed in a few weeks, well before 2.6.29 is released. The message indicates that your device has an odd number of sectors, which is rather unusual for a flash drive. I wanted to find out how many kinds of mass-storage devices really do have an odd number of sectors, and it was suggested that a WARN would permit kerneloops.org to gather some statistics. But later on it turned out that we don't need the information after all, so there's no reason to keep that warning in the code.
