I have a Raspberry PI 3 B which should be supported AFAICS but after writing the Rocky Linux 9 image on the SD card and booting the device has a high load (the below ouputs were gathered during several boots, please don’t pay too much attention to the times)
Hardware : BCM2835
Revision : a02082
Serial : 00000000c2f3133a
Model : Raspberry Pi 3 Model B Rev 1.2
[root@localhost ~]# uptime

I even waited for some hours but it didn’t get any better.
Below you can find a top output which at least at first glance doesn’t show a reason for the high load - CPU is mostly idle and IOwait is zero.

In an older forum post I found and executed the suggested commands but it didn’t reveal anything obvious to me.

Even reboot or poweroff don’t work.
[rocky@localhost ~]$ sudo systemctl reboot
[sudo] password for rocky:

See system logs and 'systemctl status reboot.target' for details.

With Rocky Linux 8.6 it seems to be working fine on the same device (same SD card).
Is there a known problem or am I missing something - any help is appreciated of course.
