With the new build it fails at later point, but I noticed I enabled
CONFIG_DEBUG_INFO_REDUCED=y
A retest without CONFIG_DEBUG_INFO_REDUCED succeed with latest latest
crash build, but there's some read errors. I'm not sure if they matters
but "bt" works well in crash.

Can you send me the location of the vmlinux and vmcore files offline?
I can
try working with them tomorrow with on an x86_64 host with a crash utility
built with "make target=ARM".
Will save the files somewher and let you know..
Thanks a lot
