vmcore-dmesg doesn't work for me, but crash did once I'd rebuilt it from the
most recent source.
The most recent commit I have is:
b349598bb755 ("Fix for the ARM64 "bt -R <symbol>" option if the only reference")
Are you using an older version?
Thanks,
James

vmcore-dmesg doesn't work for me, but crash did once I'd rebuilt it from the
most recent source.
