See http://www.freebsd.org/handbook/handbook220.html#403 for a quick reference on using the kernel debugger. Then when it hangs next time, you can drop into DDB and at least figure out where it's hanging! Perhaps you're looping somewhere in the ATAPI driver and can add a check to catch some case it's missing. The driver's author has disappeared without a trace, I'm afraid to say, so we're currently sort of winging it with this one until he makes his reappearance! :-( Jordan
