Yes, the log is correct; during the time since boot, I had just
finished downloading those 900MB of packages. In this specific case,
the interface disappeared just before or during the reboot. After the
reboot, the interface did not reappear because the hub remained
powered, and a physical reconnect was required to initialize it again.
The previous log was short because it contained only kernel messages.
This time, I am attaching the full output of journalctl -b for more
context.

thanks
