Bogus(?) /dev/sda appearing with linux-image-3.2.0-4-amd64 3.2.65-1

[Arne Nordmark <nordmark@mech.kth.se>]

With the latest Wheezy kernel I am seeing a new device /dev/sda that has
not been seen in previous kernels. Below is some info that may be of
interest.

Could it be something with RAID on the motherboard? Should it be
reported as a bug?
