Well, I had the same problem with my old motherboard.

I tried that by putting it to sleep with hdparm. It woke up just fine.

There are no spares in the RAID.
As you can see, it comes out of nowhere, there are 10 minutes between
the last entry in the log and the exception.
Hm, I could swap the drives to see if the problem is with a particular
disk or if it's with the second disk. If it's always with the second
disk, it must be a software problem. If it's not, it's probably the
disk being broken from factory.
