Yes, you have right! I try it allready, but i cannot step back enough, because my sata card works only on 2.6.16+ Before i use the promise sata cards, and the sata 300G hdds, i use 2.6.15 kernel, and all my 4 nodes was really stable. But this is not enough to exactly find the problem. :-( Anyway, Hetbert Xu helps me a lot to track down the problem, but we only can close out some thing. If i have right, the problem is about libata, promise driver, sata-error-handling or similar, but not so sure. If there is no way to software debug, i will swap all the 12 hdd between 2 disk nodes, and this can show i have right, or not.
