This morning I woke up and my pc wasn't using the nvidia driver, (usually this happens after a kernel update, I'm not sure whether the update actually happened).
Since the nvidia driver were already broke, I decided to run all the updates. I also tried to switch to nvidia drivers again, so I went into software & updates, additional drivers and selected the nvidia ones. After getting an error I decided to reboot anyway because the update required it.
After rebooting, my Ethernet connection wasn't working anymore. I tried to run the pc with the previous kernel, but the system doesn't boot up and shows:
rtl_rxtx_empty_cond == 0 (loop: 42, delay: 100)
rtl_rxtx_empty_cond == 0 (loop: 42, delay: 100)
...
some log that may be useful:

Thank you and let me know if something else may be useful. I tried all the standard stuff like rebooting both pc and modem, deleting connection etc
