System does not boot with many of Adaptec RAID controllers

Hello!

I want to pay attention to the bug 209468 [1] - system does not boot with many of Adaptec RAID controllers.
There is also growing anxiety over the absence of the driver in release 12.0.
But based on this controller built many storage and many people want to use them.
