I'm not familiar with this model or its potential firmware quirks, but this is likely a case of a drive that just can't deal with a high tag depth. You should contact Hitachi (they bought IBM's HD division) to find out if newer firmware is available for this mode. In the mean time, you might try running with a lower queue depth. You can find out about how to limit the queue depth from "README.aic7xxx" in drivers/scsi/aic7xxx. -- Justin
