On the second thought (try, actually) they are not too much helpful
indeed, as I cannot get crashdump for post-mortem analysis (when symbols
become useful), since panic happens so early debugger apparently has no
idea of where to store the dump.  It seems I have to debug it the hard way
(hello printf's).

Is it possible to cross build amd64 10.0 kernels on i386 8.3 machine?
