 What I consistently experience now is if I get any "re0: watchdog 
 timeout" messages during boot I know network will not work. A workaround 
 for me is to shut down the system completely and turn the power off so 
 the network card gets fully powered down. Then after a fresh boot it's 
 been working so far.
 I get the same issues (intermittent again) on 10.0RC2 (fresh installation).
 
 I don't get the same experience with Windows 11 nor with Fedora Linux 38 
 and 39. Seems like sometimes hardware is in an awkward state and NetBSD 
 driver doesn't do whatever it needs to do to make it sane.
