PI3 [aarch64] - one cpu core only with Kernel:Stable:Backports

Hi,

just for fun I updated the kernel-default on my Pi3 to the one from Kernel:Stable:Backports:

**$**rpm -q kernel-default 
kernel-default-5.16.11-lp153.2.1.g90630c5.aarch64

But now only one of the 4 cpu cores is active:

**$**cat /proc/cpuinfo 
processor       : 0 
BogoMIPS        : 38.40 
Features        : fp asimd evtstrm crc32 cpuid 
CPU implementer : 0x41 
CPU architecture: 8 
CPU variant     : 0x0 
CPU part        : 0xd03 
CPU revision    : 4

Here is the output from dmesg: https://paste.opensuse.org/78185050With the default kernel all cores are activated:

**$**cat /proc/cpuinfo
processor    : 0
BogoMIPS    : 38.40

And here is the output of dmesg again: https://paste.opensuse.org/23367402Has anyone an idea what is missing/not working here?

The actual error is:

[Wed Mar  2 08:09:11 2022] CPU1: failed to come online
[Wed Mar  2 08:09:11 2022] CPU1: failed in unknown state : 0x0
[Wed Mar  2 08:09:16 2022] CPU2: failed to come online
[Wed Mar  2 08:09:16 2022] CPU2: failed in unknown state : 0x0
[Wed Mar  2 08:09:21 2022] CPU3: failed to come online
[Wed Mar  2 08:09:21 2022] CPU3: failed in unknown state : 0x0

Found something on github:https://github.com/OP-TEE/build/issues/360
Not sure but it seems to be related to u-boot.
