Installing OMV trigger kernel crash on Helios64 (maybe also other rk3399 board)

Tested with Armbian_20.08.3_Helios64_buster_current_5.8.7 image and using armbian-config to install OMV.
After a while, serial console (verbosity=7) show:

existing SSH session not responding, serial console still responding and can login but took quite some time until shell ready (bash prompt appear).
command reboot took quite some time then return to bash.
