Thats the problem he was trying to get away from. the MV8 controller likes 
to offline disks when a few smart commands arrive. at least with the main 
kernel drivers. But then the main kernel mvsas drivers decide to give up if 
you even attempt to start a raid array on them. The controller locks up and 
you have to reboot. Most of the time a reboot even fails when it tries to 
sync the block devices, so a hard reset is in order.

But as I mentioned in a previous message, the driver snapshot I got from a 
nice fellow seems to work fine now. I hope it gets into the kernel sometime 
soon.
