Hi Fiery,
thank you very much for that quick and helpful answer.
I tested a lot to get rid of Problem 1). I think I got this error also with only one drive attached. But maybe it has to do something with the usage as boot raid 1. I think it occures more often in that case.
I tried the newest Intel Driver 10.8.0.1003 without success. I tried this because I found the following hint in the Intel documentation:

To resolve 3234763 the RAID OROM must be updated to version 10.8.0.1303 which is contained
in the RAID OROM and Utilities directory of this kit.
