The messages from the ELC with the disks attached were lost, but they 
were basically the same, the only difference was that there were disks 
found. The log included is from an older kernel on the ELC. My problems 
were with a newer GENERIC. Unfortunatly, the disks ar locked away right 
now, so I can't send the output from the newer. The messages for the dma 
and esp chips were the same, we checked that.
