>Description:
I have raid array with ICH7.
Reboot system when RAID1 volume is under rebuilding,
then the volume, althogh it is out of sync, is shown as READY:
 # atacontrol status ar0
 ar0: ATA RAID1 subdisks: ad10 ad14 status: READY
while "Intel(R) Matrix Strage Manager option ROM v5.7.0.1005 ICH7MR"
shows that the status of the volume is "Rebuild".
# When I boot Windows XP, it does continue rebuilding process.
