It doesn't work on my qemu+la57, kernel 4.16-rc1+. Not sure what kernel
you are testing, it truly works on kernel 4.16-rc1+ when cpu la57 is not
I tested in Linux v4.15+ and v4.16-rc2+.
The following commits in linux kernel changed mem_section array and
it causes this problem in makedumpfile.

commit 629a359bdb0e0652a8227b4ff3125431995fec6e

So when I tested makedumpfile, I reverted these commits from kernel
temporarily.
Hmm, how much memory do you reserve for crashkernel? I am afraid both of
768M as you suggested.
them need be kept in kernel, since makedumpfile need be adapted to kernel,
might be not the opposite. My personal opinion.
Yes, I agree, revert them just for temporarily tests.
So what's your plan about these two reverted commits? Will you change
it in kernel, or just leave it as is and may post another patch to fix
it?
I have no idea about it. IMO, It need to be fixed in makedumpfile
tools.
Resently, I found Thadeu posted a patch about the mem_section.
[PATCH makedumpfile] handle mem_section as either a pointer or an array
I tested makedumpfile with this patch, also can't fix the problem
BTW, it seems I misunderstood you comments, the problem I met only
happened with the following command, which we discussed before.
/makedumpfile -x vmlinux vmcore vmcore_file
Using the makedumpfile as core_collector in /etc/kdump.conf is OK for
me. So, can you gave me your error log?
I will retest this patch without reverting this two commits tomorrow.
Thanks
dou
I will take time to check this issue, maybe later. Not sure what
makedumpfile maintainers plan to do about these?
Thanks
Baoquan
supported?
Thanks
