Hi,

I've encountered this probllem with yesterday's -current: It will crash when
creating a pppoe interface (ifconfig pppoe0 create) while IPF is enabled.

It seems to happen only for pppoe interfaces, I could create additional ppp
and lo interfaces without problems.

The following log shows the boot up to the point where /etc/rc.d/network
runs ifconfig to create the pppoe interface. There are some other odd lines
that result from the minimally configured system. The crash is the same on
a fully configured system.

What's wrong here?
Please CC me on replies.

BTW: Anybody got an idea how I can save the output from qemu's serial
console into a file?

Bye, Chris
