RPi4, Kernel 5.6.x, Kodi does not start up

Start by comparing the 5.6.7+ kernel boot with the working 5.5.15 configuration and reviewing /boot/config.txt, Kodi's log, and dmesg on the RPi4. Done means identifying the kernel or configuration difference that prevents Kodi from starting under 5.6.x and confirming Kodi starts normally afterward.

Hi, having a problem and would need help please.

When running kernel 5.6.x. Kodi does not come up it stucks without any error message. If I install older kernel (5.5.15 in my case), everything works as expected. Kernel 5.6 was build from the working config of 5.5.15. System is running XBian.

It should be noted that same kernel runx on Pi3B+ without any problem

Do I miss anything? Do I have to add additional things in /boot/config.txt?
This is what I have in /boot/config.txt

[pi4]
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

Neither in Kodi's log nor in dmesg (output see below) I can see any errors, everything seems to be ok:
