Ok, seems to be pretty much random.  Updated to latest kernel, ATA_DEBUG
is off again, a bunch of boots later: sometimes it dies at random places
in the init scripts, sometimes it boots up fine, lets me do stuff and
dies later on ...

Rawhide packages (3.3.0 right now, should be 3.3.1 soon).

iommu=off seems to make no difference.
