** Description changed: When wpa_supplicant is terminated normally (i.e. with SIGTERM or SIGINT or 'wpa_cli terminate'), it brings down any wireless interfaces it is managing. However, if wpa_supplicant is started by dbus activation and if the dbus messagebus is then shut down, it terminates abruptly and improperly without deconfiguring any network interfaces. Note that wpa_supplicant has its PID file installed in /run/sendsigs.omit.d, so /etc/init.d/sendsigs makes no attempt to shut it down. Since wpa_supplicant is not supervised by upstart, it is typical for dbus-daemon to be shut down before wpa_supplicant is. This has been reported upstream (along with steps to reproduce and a patch) at: - http://w1.fi/bugz/show_bug.cgi?id=474 + http://w1.fi/bugz/show_bug.cgi?id=474 - This bug, along with a bug in network-manager (which I will report separately), means that when I connect my laptop to a wifi network, no attempt is made to disconnect from that network when shutting the system down. This in turn triggers a bug in my BIOS which causes this system to hardlock in the middle of BIOS post when I reboot while still connected to a wifi network: - http://thread.gmane.org/gmane.linux.kernel.wireless.general/102862 + This bug, along with bug 1124803 (in network-manager), means that when I connect my laptop to a wifi network, no attempt is made to disconnect from that network when shutting the system down.
