Hi, I just had a strange freeze with 2.6.31.1-rc1. Looking at the console log from startup I see that ata4 & ata5 have nothing connected. Later while working the box stalled. Checking the serial console I say messages from ata4 & ata5... There really is nothing plugged into the connectors. Any ideas on what might have happened?
