Ok, good. Now we have confirmation that it's not the SATA driver
itself that causes problems, it's some other driver.

So what I'd suggest you try to do is a "config bisect" to see exactly
_what_ config option it is that makes things break. Steve Rostedt
wrote a tool ("ktest") for this exact thing, but I'm not entirely sure
that it will work for your situation. I've added Steve to the email
participants, and I'd suggest you read up on it:

  http://lwn.net/Articles/414064/

would seem to be a good starting point.

Of course, you could just try to do it manually too - just turn one
subsystem at a time from a module in the working slackware config into
a compiled-in thing, so that eventually you end up with the
non-working "almost everything compiled in" case. And see which
subsystem it is that causes problems.

And then when you find the subsystem that makes the problem re-appear,
you'd need to go back and try each driver at a time.
