I made it a WARN_ON_ONCE(), but then always just printed the pf/hooknum. It's all over the map: reg->pf=2 and reg->hooknum=4 reg->pf=2 and reg->hooknum=2 reg->pf=2 and reg->hooknum=3 reg->pf=10 and reg->hooknum=4 reg->pf=10 and reg->hooknum=2 reg->pf=10 and reg->hooknum=3 reg->pf=7 and reg->hooknum=1 reg->pf=7 and reg->hooknum=2 reg->pf=7 and reg->hooknum=3 reg->pf=2 and reg->hooknum=0 reg->pf=2 and reg->hooknum=3 reg->pf=2 and reg->hooknum=0 reg->pf=2 and reg->hooknum=3 reg->pf=2 and reg->hooknum=4 reg->pf=2 and reg->hooknum=4 reg->pf=2 and reg->hooknum=1 reg->pf=2 and reg->hooknum=1 reg->pf=10 and reg->hooknum=0 reg->pf=10 and reg->hooknum=3 reg->pf=10 and reg->hooknum=0 reg->pf=10 and reg->hooknum=3 reg->pf=10 and reg->hooknum=4 reg->pf=10 and reg->hooknum=4 reg->pf=10 and reg->hooknum=1 reg->pf=10 and reg->hooknum=1 reg->pf=7 and reg->hooknum=3 reg->pf=7 and reg->hooknum=4 reg->pf=7 and reg->hooknum=0 reg->pf=2 and reg->hooknum=4 reg->pf=2 and reg->hooknum=2 reg->pf=2 and reg->hooknum=3 reg->pf=10 and reg->hooknum=4 reg->pf=10 and reg->hooknum=2 reg->pf=10 and reg->hooknum=3 reg->pf=7 and reg->hooknum=1 reg->pf=7 and reg->hooknum=2 reg->pf=7 and reg->hooknum=3 reg->pf=2 and reg->hooknum=0 reg->pf=2 and reg->hooknum=3 reg->pf=2 and reg->hooknum=0 reg->pf=2 and reg->hooknum=3 reg->pf=2 and reg->hooknum=4 reg->pf=2 and reg->hooknum=4 reg->pf=2 and reg->hooknum=1 reg->pf=2 and reg->hooknum=1 reg->pf=10 and reg->hooknum=0 reg->pf=10 and reg->hooknum=3 reg->pf=10 and reg->hooknum=0 reg->pf=10 and reg->hooknum=3 reg->pf=10 and reg->hooknum=4 reg->pf=10 and reg->hooknum=4 reg->pf=10 and reg->hooknum=1 reg->pf=10 and reg->hooknum=1 reg->pf=7 and reg->hooknum=3 reg->pf=7 and reg->hooknum=4 reg->pf=7 and reg->hooknum=0 and putting that through "sort -n" and "uniq -c", I get: 4 reg->pf=10 and reg->hooknum=0 4 reg->pf=10 and reg->hooknum=1 2 reg->pf=10 and reg->hooknum=2 6 reg->pf=10 and reg->hooknum=3 6 reg->pf=10 and reg->hooknum=4 4 reg->pf=2 and reg->hooknum=0 4 reg->pf=2 and reg->hooknum=1 2 reg->pf=2 and reg->hooknum=2 6 reg->pf=2 and reg->hooknum=3 6 reg->pf=2 and reg->hooknum=4 2 reg->pf=7 and reg->hooknum=0 2 reg->pf=7 and reg->hooknum=1 2 reg->pf=7 and reg->hooknum=2 4 reg->pf=7 and reg->hooknum=3 which doesn't look much better. But clearly there's a lot of those "try to unregister stuff that you can't even find". Maybe it tells you something.
