degraded array at reboot

[Jeffrey Ross]

system is running Fedora 16 with RAID 1

upon a reboot some but not all of the partitions come up as degraded and
its always the same partitions on the same disk (/dev/sda) /dev/md2,
/dev/md6, and /dev/md7 (/usr, /boot, & /home respectively, /, /var, and
swap mount with no issue)

config files are:

$ cat /etc/mdadm.conf

/dev/sd[ab]1 = /dev/md1
/dev/sd[ab]2 = /dev/md2
etc
except /dev/sd[ab]5 = /dev/md0

In the past I've tried a simple add of the partition, other times I've
tried --zero-superblock but each time after a reboot the problem comes
back.

suggestions?

Thanks, Jeff
