Comment # 3 on bug 1188019 from 
Hello,

I find the solution finally.

1. First, my rpi2 is Raspberry Pi 2 Model B Rev 1.1, which use a different CPU
from Rev 1.2.
2. I reinstall Raspbian Buster lite, there is no this problem (using DHCP). So
my rpi2 is not broken.
3. Then I reinstall to OpenSUSE 15.3
(openSUSE-Leap-15.3-ARM-JeOS-raspberrypi2.armv7l-2021.05.31-Build8.1.raw.xz)
   If I use DHCP, there are huge of logs like these, and CPU still very high

So I set static IP to this rpi2:
> cat /etc/sysconfig/network/ifcfg-eth0
> IPADDR='192.168.60.120/24'
> BOOTPROTO='static'
> STARTMODE='auto'

> cat /etc/sysconfig/network/ifroute-eth0
> default 192.168.60.21 - eth0

Then the CPU comes to 0 now. :)

and "journalctl -n 10" do not show these DHCP infos.

So, somethings wrong with wicked dhcp? Or is it normal that wicked will cause
high CPU when request DHCP?
