I don't have access to a BUS analyzer right now, but here is my regression. 1. Hook an external SCSI array/disk to a 29320. 2. Power up SCSI array/disk 3. Power up PC with 29320. 4. When PC has booted, login and test device by creating a file system, eg. mkfs /dev/sda (or whatever disk the array is called on ur machine). 5. Power cycle array/disk 6. Retest device with another 'mkfs /dev/sda' ... panic/crash/lock-up ensues. This did not happen in 2.6.15.7 but did appear in 2.6.16 and higher. Any ideas? Sean
