There is a reasonably good description of the history and format of the
dump file in the comment block at the beginning of dump_base.c in the
LKCD kernel patch (at least it's there in the
lkcd-4.1-1-2.4.18.patch.txt version that I am using). Details of the
various headers that constitute that format can be read in dump.h.

There are to my knowledge two analysis programs that can be used to
analyze these dump files:

	lcrash; and
	crash

I use crash since there is a PowerPC port of crash that sort of works
whereas lcrash does not to my knowledge have a PowerPC port. If you are
intending to run LKCD on an x86 target, my guess is you can use either
lcrash or crash.

crash uses gdb as part of the analysis it does, but gdb by itself is not
sufficient.
