I don't know if this is the right way to correct this problem. If someone tries it, he tries it at his own risk.
In the RECALBOX
partition, on the config.txt
file, i change the 3 lines of :
dtoverlay=vc4-kms-v3d
to be
dtoverlay=vc4-fkms-v3d
save the file and restart. I am testing the system two hours now without a freeze so far.
