Maybe there are more than one controllers on board?
You could try setting sataportmap to 44.
Your sata controller is a C226

Only one controller for 6 sata HDD
Use : sataportmap=6
I try that but i still get the error that HDD 5,6 are damaged and sata ports are disabled ....
when i boot up with the old 5.2 everything is fine
