It really doesn't have to check all since it knows h= ow many target there are (72 in my case) - it could stop after having detected that many...=20 (No wonder the Linux folks have replaced their cciss driver with a rewritten one called hpsa). - Peter --=20 You are receiving this mail because: You are the assignee for the bug.=
