aac0: Error 5 sending VMIoctl command

[Kent Ketell]

Hi,
 
I have been running various flavors of FreeBSD for a few years now with
the Adaptec 2200s raid controller.  When the controller is busy I often
see "aac0: Error 5 sending VMIoctl command" on the console during boot,
but lately it started happening even when the controller is idle.
 
The systems in question are Supermicro w/dual 3.6GHz processors, a
single 36GB for boot and six 18GB disks in a stripe.
 
Here is the dmesg noise from boot:

As you can see, the system does eventually come up, but it takes a good
long time to do so.

I have the right stuff in the kernel for the controller:
device       aac
device       aacp

Any thoughts?

Thanks.
