Right, but something is fundamentally wrong with your
vmcore:
p_paddr p_filesz
First segment: 0 8000
Second segment: 8000 1ff7fff
Third segment: 2fd0f001 d02f0fff
It cannot have a p_paddr address that is not page-aligned,
nor can you have a p_filesz that is not page-aligned.

Vivek et al,
Have there been any recent changes to the kdump code
that might cause strange PT_LOAD segment contents?
Dave, As per my knowledge nothing has changed. Generally PT_LOAD headers are
generated from user space while kernel is being loaded and second kernel
leaves them untouched except updating the offset field. So there are
high chances that user space itself is not generating right headers while
loading the capture kernel.
Dave Wilder, can you put some debugging statement in kexec-tools and see
what header values are being generated from user space and do they match
with what /proc/vmcore is showing.
I will do some experiments on x86_64.
Thanks
Vivek

I lost the system for the day. But I should get it back on Friday to
try your suggestion.
