I'm paranoid. I do "make distclean" when doing anything other than
adding/removing drivers. Save/restore the .config if you need to before
running "make distclean".  I don't trust the Makefiles to rebuild
everything correctly for "global" CONFIG_ changes like "SMP".

SMP on 2.4.19 isn't as stable yet.  So that's no surprise.

If you want to debug this further, define "EARLY_BOOTUP_DEBUG"
in arch/parisc/kernel/pdc_cons.c and you should get more output
about how far the kernel gets before it crashes/hangs.
