[K12OSN] Kernel Panic with SATA RAID

This sounds like what is happening to me.  I assumed that for some
reason the kernel saw the SATA as a SCSI controller and the reason for
the crash is the driver or something isn't right and since it can't
access the data correctly the kernel panics and I am done.  

Any ideas on how to fix this or should I look at purchasing a new
controller that is known to work?  If a new controller is the only way
does anyone know of a SATA controller known to work?  At this point I
would rather eat a few hundred bucks than delay the server too long.

Thanks
