I am running into data integrity issues while running sgp_dd ver 1.20 against any sg device while running 31 threads. kernel 2.6.28 Ubuntu. When running it in slow speed (20 MB/s) all runs well. When pushing it towards the 50MB/s , Data integrity issues appear. When running it against sd devices - no integrity issues , but bpt is not determined and changes . Any idea how to fix the sg data integrity issues?
