Now that netpoll has been disabled for slaved devices, is there a
recommended method of running netconsole on a machine that has a slaved
device?

Yes, running it on the master device instead.

Thanks for the suggestion, but:

Is there a way to control or associate network device names prior to
udev renaming?

That looks like a systemd problem (or more specifically a boot dependency
problem).  You need to modify your netconsole unit/service file to start after
all your networking is up.  NetworkManager provides a dummy service file for
this purpose, called networkmanager-wait-online.service

Thanks again,
