So I applied this patch and it works fine.
However I cannot say if this fixed it. The warning does not appear, however,
it's probably possible that the drive does only return a wrong blocksize
under weird conditions (firmware bug).

So in any case, I think this patch should be applied. Checking device sanity
is always a good thing.
