I have stumbled upon error which I have not experienced in Debian Buster on the same hardware and same kernel series.
Description: After PC restart, ethernet doesn’t work. Only solution to restore it, is to turn off PC completely and start again, or suspend to RAM and start again.
dmesg is catching NETDEV WATCHDOG exception and says:
