>Description:
Two SATA drives are used with gmirror to do mirroring.
When I stress atacontrol with attach and detach, my system freezes and I can just reboot the machine.
The problem occure during atacontrol detach or atacontrol attach.
>How-To-Repeat:
while true;do
atacontrol detach ata3
atacontrol attach ata3
done

If messages are displayed during this test, it is more difficult to freeze the system.
