 I have an ASUS p5b deluxe. In raid 5, with 4 identical disks, if I do
 # atacontrol detach ata8
 when freebsd is up and running, after 1-2 minutes, system can't access to=
  the disks. Is needed a reset, but at the boot, the system reboots, in lo=
 op.
 The only thing I can do is to boot from the installation CD, run a shell =
 and type this command
 # ln -sf /mnt2/usr/bin /usr/bin
 # ln -sf /mnt2/bin/dd /stand/dd
 then run atacontrol:
 atacontrol detach ata8
 atacontrol attach ata8
 atacontrol addspare ar0 ad16
 atacontrol rebuild ar0
 
 but output of # atacontrol status ar0 is always
 ar0: ATA RAID5 subdisks: ad10 ad12 ad14 ad16 status: REBUILDING 0% comple=
 ted
 
 Also if I make a RAID 1, rebuilding don't start.
 Motherboard: Asus p5b deluxe
