Eth0 down/up failed in JP5.0.2

[779784017]

Hi:
I use sdkmanager to flash jp5.0.2 to xavier-nx on dev kits, when I login system and use the command “sudo ifconfig eth0 down” and then “sudo ifconfig eth0 up”, the eth0 will open failed, I cannot find eth0 in ifconfig(it can be found in “ifconfig -a”),so I have to reboot or reset the device.
I have tried jp4.6.1 and down/up the eth0 many times, it works well. This seems to happen only in jp5.0.2.
I want some help to check and solve the problem.
I will attach the dmesg.log,
dmesg.log (68.4 KB)

It failed to get eqos clk. I don’t observe this on my xavier nx devkit. is it easy to reproduce on your devkit?

Hi：
Thank you for your reply.
It seems very easy to reproduce on my devkit. I flashed the devkit many times and the problem still appears.
