We dropped LSI in favour of Adaptec for exactly this reason. We run hundreds of machines in remote locations, and always again had problems with LSI regarding support of new controller models and kernel versions (esp. on system installation), and because of occasional kernel panics triggers by the LSI driver. The Adaptec-support integrated into the Linux kernel source tree does a flawless job here. On the other hand, Adaptec is not perfect as well: when we attached a 24-drive SAS storage unit to a 5805Z, it failed to properly handle drive failures in this unit. We are using an LSI again there, which so far works well... Joachim
