Could you try to do two things for me? Using (preferably from a recent e2fsprogs, such as 1.41.11 or 12) run filefrag -v on the files created from your 2.6.27 run and your 2.6.32 run? Secondly can capture blktrace results from 2.6.27 and 2.6.32? That would be very helpful to understand what might be going on. Either would be helpful; both would be greatly appreciated.
