Possible problem with PROMISE ide-raid integrated on Asus mobo (+ solve)

Hi, I own a Asus A7V133, and it has a promise Fasttrack100 integrated on the board. When installing SuSE 8.0 pro, things go bad when configured as a raid cluster. When partitioning the raid cluster (/dev/ataraid/d0) somehow the new partitiontable fails to sync to the disks. It is written to the disks, but not refreshed for the OS, which results in a failure to format the partitions. Rebooting the machine AFTER having partitioned the raid-cluster (and the errors that formatting failed) and restarting the installationprocess using the partitions as layd out in the previous install-run, results in a successfull install. hope this helps, Gr.
