Hello everybody,
I'm reporting a problem that looks _very_ similar to one reported on
freebsd-current@ last year, by Pawel Worach:
http://lists.freebsd.org/pipermail/freebsd-current/2008-January/082581.html
My system is a 6.4-STABLE, with up-to-date /usr/src and /usr/ports:
$ uname -a
FreeBSD diavoletto 6.4-STABLE FreeBSD 6.4-STABLE #19: Mon Feb 16 12:01:24 CET
2009 r...@diavoletto:/usr/obj/usr/src/sys/GENERIC i386
In /etc/rc.conf I have the following lines:
> dbus_enable="YES"
> hald_enable="YES"
Every time dbus is started, if consolekit-0.3.0 is installed then a
page fault occurs just after the login screen is shown. If I "make
deinstall" the port in single-user-mode, then the system boots and
works fine.
If I boot with consolekit uninstalled, then install it and restart
dbus, I get a panic.
I'm reporting here the same information that Pawel Worach reported
last year for his problem. Please tell me if I can provide any more
information; this is my very first problem report here!
