The kerntypes file that crash can use is built by the LKCD
dwarfexract
command. Types are extracted from a -g kernel and modules. And dwarfextract
writes a magic ELF e_version that crash uses to distinguish a kerntypes from
a vmlinux. So only such a kerntypes file will work.
Also the standard -g compiled lkcd Kerntypes file seems to work, if you
set the KERNTYPES flag. This can be useful, if you don't want to build a
full -g compiled vmlinux.
I used the following simple patch which adds the "-k" option to force
crash using the kerntypes code path.

I attached the kerntypes file, which works for s390:
