Hi, i have been running linux on rk3399 booted with kexec fine until 5.2
From 5.2 onwards, there are memory corruption issues as reported here:
http://lkml.iu.edu/hypermail/linux/kernel/1906.2/07211.html
kexec has been identified as the principal reason for the issues.

It turns out that kexec has never worked reliably on this platform,
i was just lucky until recently.

Please, can you provide some directions on how to debug the issue?

The latest test performed is:
 1.- Boot v5.3-rc1
 2.- Kexec into v5.2.2
 3.- The kernel reports nothing (earlycon not enabled) and does not boot.
The same kernel v5.2.2 works fine when booted without kexec.

Regards,
  Vicenç.
