[16596.763807] net_ratelimit: 9 callbacks suppressed I already tried to build realtek ether driver by myself r8169-6.031, doesn't work for me. All I think we need to narrow down the scope the issue belong to kernel upgrade or driver itself? In my case, it's working good on kernel 5.15 Current workaround is take another USB network card.
