Bug#594418: new mdadm version causes high I/O during boot, boot fails, perhaps issue with udev rules

[Darren]

Alexander,
Should that bug be related to #594472 and #595061, as you anticipate,
I can confirm that upgrading to mdadm 3.1.4-1+8efb9d1 from sid solved
it in my case. Details can be found in  #594472.

regards
   Darren
