I don't think there's any particular problem with booting stripped
kernels (modulo some problems reported with strip recently).  But I
agree wholeheartedly that bug fixing is a pain without a minumum of
information.  What do people say about making something like this a
policy?

1.  Build a kernel with debugging avaialable.
2.  Enable dumps.
3.  If you wish, strip the kernel before booting, but keep the debug
    version in /var/crash for later analysis.
