Hi.
My system is crashing when I log out (using gdm). I had posted to gnome but was
just advised to post to x11, posted to x11 and was told this is a kernel bug.
Many thanks for any all of your assistance. Backtrace is provided below.

Backtrace is provided below.I had similar problems (didn't do a backtrace though). Solution was updating to 7-stable and adding dbus_enable="YES" hald_enable="YES" to rc.conf. Updating might not be necessary, adding dbus and hald is absolutely. regards hendrik -- Dr. Hendrik Bunke blog: http://hbxt.org/ com: http://hbxt.de/
