 What's in the tree now is just a work around but the underlying
 problem still exists and is yet to be solved so it's appropriate
 to leave this PR in an open state. I'm not sure what's the best
 assignee though; as it turned out later this problem isn't
 sparc64-specific at all. As it's ATA_CAM related mav@ would be
 best, but he unfortunately doesn't seem to be interested that
 much in fixing it ...
