Nah, its because of some work I did last year to propogate maximum
I/O block sizes upwards from the device instead of hardcoding it
in the kernel. I did about half the work, set up the defaults, but
didn't get around to converting the drivers. This was because,
at the time, I wanted to figure out what the drivers could actually do.
In anycase, its a harmless warning, just ignore it. We'll get the
drivers fixed at some point.
