I've followed the procedure at
http://www.vinumvm.org/vinum/how-to-debug.html, and now I have some more
symbols (look at #28, #29 and #30). Unfortunately, the output of 'f 1'
does not have de "vinum debug" line in it, I don't know if it should (I
was going from singleuser to multiuser when the panic took place).  My
debug environment is (long lines):
