    I tried kdb, and it's got the same problem as "crash".
     
    If I knew enough about the AIX internals I guess I could just look at the
    raw data - I used to be able to do that for MVS systems, many moons ago -
    but I don't, so I can't.
     
     
    I do still have a mksysb taken before I started work. Could I restore /unix
    from that (to some other name, of course!) then use that as input to the kdb
    command? e.g. kdb /dev/hd7 /old_unix
     
    If I can find the time I might give that a try.

Unfortunately, I don't think so. It needs the correct kernel file to resolve
symbols and to have a consistent state of the system at the time of 
the crash. If there is a way, I'd really like to know. I ran into that once
before as well. Because of it I never knew the cause of a system crash. 
        Also, this may be worth it. "kdb" actually existed in some later
levels of 4.3.3. Go ahead and try it on that. I highly doubt it though.
