Actually, for me, 2.0 is extremely stable -- the only problem I'm
having is since 220.127.116.11, where I am having problem launching it. It
doesn't "crash" in a traditional way, though. It's like it starts, but
the window manager has run out of window handles or something. The
process is running. I can see it in the process list (though it doesn't
show up in WindowMaker as an icon).

Yes, well.. That's a ... big file. :-)
I have been recommended to run ktrace before, in relation to another
problem. But I don't really understand the output of kdump. What does it
do? Does it dump all system calls, including parameters?
While I'm on the topic.. I learned kernel debugging through a
tutorial written my IBM (this was on OS/2). Is there any kind of
intro/tutorial to ktrace/kdump somewhere which just quickly outlines
what everything is, and some small examples?
