Hm, I have applied a fix similar to this one:
I'm not sure if it's a coincidence or not, but I had no panics since
then. Packet loss rate are still very high - first packets go through
without losses, but eventually loss rate goes up.
Now uptime is 1 hour and loss rate is about 80-85%.
Any directions how can I debug this?
