SUSE 64-bit + 3ware controller = Corrupt filesystem

Hi, I am seeing filesystem corruption when attempting to test a 3ware SATA raid adapter with SUSE 9.0 professional 64-bit. In particular, if I mount the array and then copy a bunch of files from the root filesystem (which is on a standard IDE drive) random files _on the root filesystem_ get corrupted. This happens with both the driver shipped on the DVD and the latest driver from 3ware. I also tested with both ext3 and Reiserfs. Can anyone verify that the 3ware adapter is working with this release? This is on a Tyan K8W board. Mike
