first. This will fix a few cards that hang on the WD probe. He tells me that PAO went one step farther and removed the WD proble completely and none of the cards in the 2.x database broke in PAO3. Since I'm more conservative in this code, I'm just swapping the order, which he said also fixed his problem. Reviewed by: mdodd, iwasaki Submitted by: sanpai@sanpai.org
