Since I did not compile the kernel myself, ksymoops is not too happy with
what is has to analyse the dump. I tried compile the Mandrake kernel myself
but there seems to be something unmatched. See below for what ksymoops
gives me.

Warning (compare_maps): mismatch on symbol vt_cons , ksyms_base says
c02b06e0, vmlinux says c02ac6e0. Ignoring ksyms_base entry

(I get about > 300 msgs of that kind)

Let me know who I can prepare for the next crash with my own kernel. Are
there any options I have to turn on for compiling?
