Right now I'm using only 4GB RAM. As Scott said, problem is below: "The ips driver looks like it will fail under heavy load when more than 4GB of RAM is present. It tries to force busdma to not defer requests when the bounce page reserve is low, but that looks to be broken and will result in corrupted commands." Are the ips driver and bus_dma problems fixed yet? Can somebody tell me the future plans in this regard? My boss is really pushing me to use all 8GB of RAM on server:( thanks in advance, Ganbold
