This went into Linux tree - and broke my ia64 box in a weird way. It only
sees one of the two disks.  git bisect points to this commit, and reverting
it fixes the problem.

Attached are serial logs from the "bad" boot (tip of Linus tree = b79013b2449c)
and for a "good" boot with this commit reverted.
