Dangd high-falutin' english. What I was trying to say (with the word
"so") was that when the kernel crashes in this manner, though I do have
ddb in the kernel, and can ask for a stack trace, all I get is
something like:

... (forgot if there was some dispatcher listed here or not)
address error catcher

I'm adlibbing a fair bit, but the sticky point is that there's NOTHING
listed after the address error catcher.

If I'd been able to see what part of the macfs code was illing, I'd
be asking for help with it. :-)

Take care,
