Putting that into /etc/sysctl.conf results in a solid hang on bootup
here, right after IP Filter init and before the interfaces come up:
(...)
IP FIlter: already initialized
ipmon
ipnat
0 entries flushed from NAT table
0 entries flushed from NAT list
.
[HANGS HERE with kern.polling.enable=1 in /etc/sysctl.conf]
dc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.8.1 netmask 0xffffff00 broadcast 192.168.8.255
(...)
Attached is kernel config, (normal) dmesg. Everything seems to work fine
if I enable polling after booting though, so maybe this is 'correct
behaviour'?
Greetings,
Michael Nottebrock
