I rebuilt the kernel with Ken'ichi's kernel patch he posted on 8/31 on
"Fix the difference between node_mem_map and node_start_pfn". I also
used makedumpfile-1.2.9 & crash-4.0-7.1. I did not see the complaint
"Can't distinguish the pgtable" from makedumpfile this time.
Crash failed to come up again, on error:
page excluded: kernel virtual address: e0000060031417a8 type:
"zone spanned_pages"
Still, crash was able to come up with vmcore by 'cp'. How do i verify
the "zone spanned_pages" from crash analyzing the vmcore from 'cp',
Dave?
