Hello,
I'm experiencing the same (http://www.mail-archive.com/freebsd-stable@freebsd.org/msg101997.html
) after updating to last hald in 6.4-STABLE.
Anyone tried to fix it with the Kostik Belousov patch as in http://lists.freebsd.org/pipermail/freebsd-current/2008-January/082581.html
?
Any other fix ?
cheers

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... at 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!
