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?

You might try the new aacraid module: 1.1.5[2371] from Adaptec's site. I
had some newer firmware that combined w/ the stock 1.1.2-lk2... got the
exact 'SCSI hang ?' msg... w/ the new module no such problems. 2.6.9 is
stable for me except it seems I don't have the write performance I
should yet (see my last post).
Hope this helps.

Known bug in the 2.6 aacraid driver. It's fixed in current Fedora Core 3
kernels, 2.6.10-ac or in 2.6.11rc1. I've attached the needed patch below
