You need to find out why sdb is busy. Maybe look in /sys/block/sdb/holders. Maybe some filesystem on it go automagically mounted by mistake or something. Maybe send: cat /proc/mounts /proc/swaps /proc/mdstat /proc/partitions find -H /sys/block/sdb -ls and we can see if there are any hints. Maybe send full kernel logs from the boot sequence as well.
