Looking on on your first and later posts I would say that this commit may happen not a root of your problem. It may just trigger something else. Problem begins when some of your drives on ata1 channel timeouts request that leads to several controller reinits. I think that durung that driver somehow gets wrong drive parameters that leads to division by zero error inside ata_tf_write(). I have just committed one patch that probably does not fix the problem, but change process a bit. Could you try it and send me all ata related verbose messages starting from controller detection. -- Alexander MotinReceived on Thu Feb 26 2009 - 20:58:23 UTC
