I'm reopening this bug because it reproduces with the latest release,
which seems to have the fix released on 2008-12-03. I'm running a
default install of Xubuntu 9.0.4 on a Sony Vaio VGN-G2.
Problem: the system hangs during reboot or halt if there is an active
wireless connection. During reboot, I get the following message
* Stopping anac(h)ronistic cron anacron
acpid: exiting
nm-system-settings: SCPlugin-Ifupdown: devices removed (udi:
/or/freedesktop/Hal/devices/net_00_1a_80_d6_06_5a)
nm-system-settings: SCPlugin-Ifupdown: devices removed (udi:
/org/freedesktop/Hal/devices/net_00_1f_3c_85_77_4a)
nm-dispatcher.action: Caught signal 15, shutting down...
The first line is sometimes different, but I can't seem to get the alternative
message at the moment.
The system makes no further progress. For halt, the message is just "acpid:
exiting\n\n", or sometimes it's just blank.
The system is not completely frozen; the Enter key advances the cursor and the
console is blanked after inactivity (and lights up again in response to a
keystroke). Ctrl+Alt+Delete seems to be registering---it doesn't cause the
system to make progress but after repeatedly pressing the combination, I see
"init: control-alt-delete respawning too fast, stopped".
The reproducibility is not 100% although it's fairly high, well over 50%
(subjectively; I didn't acutally count).
The problem goes away if I link /etc/init.d/NetworkManager from rc0.d
and rc6.d. I used the prefix K88 following Debian, but perhaps a
different number is more appropriate for Ubuntu.
** Changed in: network-manager (Ubuntu)
