aacraid fails when RAID1 array is in anything but Optimal state

    We're using Dell PowerEdge 750s with a Dell rebranded Adaptec CERC 1.5/6ch
    SATA adapter. The systems have 2 disks configured as RAID1. If the array
    is in any other state than 'Optimal' (ie. 'Degraded' or 'Rebuilding') the
    following error is displayed and the box subsequently panics because its
    unable to mount the root filesystem.

    We've had the same experience with 2.6.7 and 2.6.9. Yesterday as a test,
    I installed RedHat ES 3.0 and it does not exhibit this behavior, but thats
    kernel 2.4 with different aacraid driver. We've also updated to the
    latest recommended firmware in attempt to correct this.

    Is there any way to make this work with kernel 2.6? Or is this expected
    behavior for this controller under 2.6?
