Hi Dave,

Ugh... :-(
At boot I get:
...
INIT: Entering runlevel: 2

Starting enhanced syslogd: rsyslogd.

Starting system message bus: dbuseth0: Setting full-duplex based on MII#1 link partner capability of 41e1.

Starting OpenBSD Secure Shell server: sshd


Backtrace:

I'm not sure if this relates to your patch though...

Anyway, the machine is located at work and I can't restart it remotely.
I'll test it again tomorrow...
