I do the best that I can in the amount of time that I have. I welcome others to learn about the Adaptec aic7xxx controllers, review the code, and help fix the bugs. I do hope that you will at least try the revision that was just committed to the tree. Althought I may not have fixed all of the problems with it, I know that there are fewer bugs than earlier releases. I don't like the hangs and bugs any more than you do, but I do take pride in my work and will continue to do all I can to ensure a robust driver. -- Justin T.
