I will send you patches; you will not be able to trigger the buzz-flag to throw the second processor into the scheduler, however. The second processor LDT/GDT is incorrectly setup in my patch set; I would be happy to have you fix it for me. I either need more hardware (like an ICE I can plug into the second processor slot), a significant amount of assembly that I'm not going to write right now (basically a BSD version of "SoftIce(tm)"), or to sit down and line-by-line analyze what is getting set on which when and by who (which means I'd probably dike out all the existing and uncommented debugger and tracing code, a bad thing). This last one might be a reasonable thing, if we weren't in crunch-mode at work. I don't have time to "play computer", let alone "play SMP computer" on 30+ sheets of engineering paper. 8-(. Right now, I'm concentrating on kernel multithreading and file system reentrancy, in specific. It's all work that needs to be done.
