Hi, I also bought an ASUS M3A78 mATX board with a SB700 to see if it might solve my problem with the SB600. But it doesn't. The SB700 shows the same behaviour as the SB600, it periodically throws an error and the power cycles the disk. But it always happens on one channel not both. Perhaps a sudden burst in disk IO causes this but I'm unable to reproduce this with a synthetic load. Only when vmware is running this happens. I don't see it when the machine is idling. The load on the machine is very light both on cpu and disk. Also I didn't see the error with a single seagate disk attached. The error and configuration is the same as mentioned in my earlier post regarding the "SB600 AHCI causes disk power cycle". What I didn't mentioned then was the filesystem layout two disks in a mirror /dev/sda & /dev/sdb no LVM just a software raid via md md0 /boot ext3 md1 / ext3 md2 swap md3 /usr/local/virtmach XFS Please let me know what else I need to log and/or test.
