We have custom hardware here with integrated 6081 controllers and a uniprocessor board. The driver was developed and tested solely on that platform and works very well for me. However, I haven't had the time to try it on normal 6xxx or 5xxx HBA cards (like everyone else in the world is using) or on an SMP system. It's been something I've been meaning to do for some time now. Compounded with that, I've decided to leave my current position to pursue my career at another company (still doing Linux kernel development but in a different area). Thus, I will be less focused on the driver and might not have access to HW and specifications. I know there are others on this list who do have both of those necessary requirements for development so it's possible they can help pick up the slack. In the meantime, try turning off SMP and seeing if that makes a difference. There still might be a problem with the spinlocks and if so it should go away in uniprocessor mode.
