Hi Patrick, You have hit on one of the key word of my downfall. Specifications!!! I believe in them and they are the inflexable state machine which all OSes are required to address. Linux has a very bad history of avoiding the boundary conditions related to storage. I am for following the rules of the spec, and will bet Linus would now agree more so than before. The problem is SCSI is a strange beast without a formal FSM. It is more of a BusPhase psuedo stated transport. It is smart enough to laugh at bad software designs and keep going. Sheesh, look at M$'s miniport. This leads me to a point where a similar (but smarter) miniport could look interesting. However, this is also where the transport classes have their bases, afaics. Anyone please correct me where I have mistated (other than Linus, :-p). Luben, I have a vested interest in seeing SAS run via SCSI. So this means you have one ex-demi-god from the world of maintainers looking to pull you have towards the current path and open to ideas and willing to back a better design and push it.
