Hi Tom, It looks like I'm falling over a similar problem to you in bug 68888; in my case I think the problem is it doesn't like the format of my mdadm.conf; but could you add to your report; the output of :
cat /proc/mdstat and then for each of the partitions with the RAID on the output of mdadm --examine /dev/xxxxx (Where /dev/xxxxx replaced by your disc device). -- mdadm causes boot to hang for 4 minutes https://launchpad.net/bugs/67299 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
