 And today I used netbsd-5 a while with re0 disabled, without issue
 whatsoever.  Then I enabled re0 and three times I could reproduce the
 issue and recover by quickly disabling the interface before the system
 was permanently frozen.  Interestingly, I also left a systat-vmstat
 command running and I could not really notice abnormal pin interrupt
 floods.  However, top will show two of the cores in "100% interrupt"
 and the two others in "100% system", as usual.
