Unless somebody broke something, this is certainly not a GEOM bug,
because GEOM will access any sectorsize >= 512 bytes, and by "any"
I don't just mean power-of-two sizes.

Run:
	diskinfo -v /dev/da3
and see what it says.

If it says anything but 1024 byte sector size, the problem is in
scsi_da or umass, possibly both.

If it says 1024 byte sector size, somebody broke GEOM.
