That's a GOOD thing.  Making all drives appear using a consistent
interface makes things much simpler in general.  Also libata is much
better than the old IDE system in terms of handling errors and such.

By the way they are not appearing as scsi, simply as devices with a scsi
style interface, just like USB, firewire, and lots of other things have
already done for years.

So what you are seeing is simply a result of moving to new and better
drivers with a better interface.  It is not a bug at all.  The fix is to
convert your fstab and boot settings to use the new drive names.
