We use 3ware/LSI 9650,9690 and 9750 controllers a lot and have rarely had any problems. The problems we encountered came with hardware failures. On the LSISAS2008 it's good to hear that most problems got fixed with later kernels. As we are trying to get our lower-cost storage systems running on this controller (onboard a supermicro MB), this shows which way to go... Thank you for this information!
