Here are the messages: > Hi Ludovico, Thanks for the report. The AS messages should be harmless. The warn statement is an incorrect assertion (I'm actually surprised the only reports of it are IDE TCQ). It should not be the cause of the attempt to access beyond the end of device messages. I think IDE TCQ is not 100% stable at the moment (Jens?) and you have to do things like ensure only one drive on the cable (not a master and slave). Your best option is to turn TCQ off. You could try booting with the argument elevator=deadline, however. That would fix it if it were an AS problem.
