initcall_debug makes no difference.
Going back to console=ttyS0 it seems that enabling serial console
gives a 100% boot success ratio. Unfortunately this means that I
can't capture the error with a serial console. This evening I'll
try with a 60 fps camera to see if I can get more info.
Regarding the point of failure I see that sometimes the boot is
stuck with an empty screen, sometimes it outputs the attended
stack trace (always booting with the same kernel command line
obviously).
Kind regards
