Hi. I state that this problem is present from kernel 5.4 and still has not been fixed ... suddenly, the ethernet stops working and this error appears (in dmesg):

i have no idea what might happen to generate this error. I noticed that it happens when I restart the PC a couple of times. Many people have this problem. I can't currently use ethernet!
Thanks
