Unfortunately looks like indefinitely. Never watched longer so far
(rebooted soon), but I'm seeing this message now repeated every 10 secs
for ~10 minutes on a idle system.

Ugh.  A real bug then.  These can be a pain to track down and fix. I
think the last one of these I tracked down took a couple of weeks.  I
will start digging in when I get back from vacation.

I once spent a similar amount of time putting in debug variants that
printed info for each time a netdev was acquired and released.

Maybe a similar logic could be put into the official kernel (and
disabled by default)?

That should save effort in the long run, I'd think.

Thanks,
Ben
