I have been trying to use crash dump with your branch without much
success on juno-r2:
WARNING: could not find MAGIC_START!
crash: cannot determine base kernel version
crash: /root/vmlinux and /root/coredump.kernel do not match!
Looking at the debug log (-p 5), the translation va -> pa computed by
crash is wrong.
The physical address expected is 0x80a76b28, but crash return 0x88a76b28.
I am using crash built from  and the panic has been created using
Also, crash dump seems to always report that Xen is running even when
KVM was in used (see logs ) below.
Lastly, crash fails with an error after a couple of minutes (see logs ).
How you seen such errors during your testing?
