OSKit-Mach used to show a dump and wait for the user when it
crashed. I think this was when I used earlier versions of the OSKit
and that this problem is some unfixed bug in the 20010214 snapshort of
OSKit or in OSKit-Mach itself which triggered by the new
version. (Just like the previous problems with the new version, I
recall it was the interrupt code and it might be related)

I don't really remember in what function I made the change and I
deleted the change when cleaning up my directories of sources. I think
it was in one of the following files:

In $(oskit)/libc/gen/panic.c (this is the OSKit, not OSKit-Mach) there
is a call to getchar(). It should wait for you pressing a key. For
some reason this doesn't work.

In $(oskit)/kern/x86/pc/base_console_init.c the fuction our_exit() is
called. You could add a call to getchar() here.

In $(oskit-mach)/oskit/x86/main.c (Note that this OSKit-Mach and not
the OSKit) the function my_exit() is called before rebooting IIRC. You
could also add a call to getchar() here.

Remember that OSKit-Mach is still experimental and gnumach should be
used when possible, unless you don't care about kernel crashes and you
like kernel debugging. This also counts for building OSKit-Mach (and
OSKit). There is some documentation,
http://www.etherhogz.org/doc/oskit-mach.html, but I don't know how
up-to-date it is. In the future (read: when we have a good console in
OSKit-Mach) there will probably just a debian package like gnumach at
the moment.
