Unfortunately we did not find a fix for the PERC H200. Our solution was to purchase a LSI MegaRAID 9240-8i and compile a kernel with the FreeBSD driver provided by LSI. At the moment we are running 8.2 stable with this controller and we have not suffered any issues re stability. One thing to note if you choose to do this and you are using a similar Dell chassis to the PowerEdge R515 we have is that the LSI card is larger than the PERC H200 and must be connected to a PCI-E further from the SAS backplane. We needed to purchase longer SAS SFF-8087 to SFF-8087 cables to make the distance. Hope that helps, John (Attila's colleague)
