Agreed. But RHEL/Centos doesn't update "their" kernel as much as the main tree. And, I'm not really willing to have a much different and less tested kernel (in RHEL/CetnOS context, that is) as the one provided by default. Anyway, I was just willing to let you know that the fix works fine with others than 9550 controllers ;) Regards, Laurent.
