I think I found the problem. The freeze is caused by the

At least the kernel is booting after changing it.
And it was only set to "y" for the 5.3.18-59.25-default kernel used in 15.3

Hi all,
I tested the U-Boot fix for several versions and it works perfect for
all of them.

But it looks like there is an additional problem with Leap 15.3 which
freezes at boot.

Deasserting all peripheral resets
[freeze]
I also upgraded a fixed Leap 15.2 to 15.3 and the same thing happens
(Only
without the "Deasserting all peripheral resets" message) for kernel
5.3.18-59.25-default. The older kernels 5.3.18-lp152.95 and
5.3.18-lp152.92 are booting without any problem.
Any ideas how to debug this further?
You can try to get more output by editing the kernel boot parameter in
grub. Try 'earlycon'. If that does not help, try 'earlycon efi=debug'.
Beware that you
might need to pass memory region of your serial console to the earlycon
parameter. Have a look at:
https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html
