Bug Description
Binary package hint: network-manager
I run the latest Gutsy on a T61 laptop with ipw3945 wireless.
Suspend usually works, but every now and then the system gets stuck in the dark-screen-
[27494.464000] PM: Preparing system for mem sleep
[27494.464000] Stopping tasks ...
[27514.468000] Stopping user space processes timed out after 20 seconds (1 tasks refusing to freeze):
[27514.468000] NetworkManager
[27514.468000] Restarting tasks ... done.
I can unlock the screensaver and ask the system to suspend again, which works fine. After a resume network manager is oblivious: doesn't perform network scanning, shows an outdated list of wireless networks, ignores my attempts to disable/reenable it. Restarting NM with
sudo /etc/dbus-
sudo /etc/dbus-
helps. But this is a minor irritation; the major thing is that NetworkManager sporadically prevents the first attempt to suspend.
I'm used to press Fn-F5, close the lid, wait a couple of seconds to give the system the chance to sleep, then stash my laptop in my backpack. Three or four times already I discovered my laptop running hot in the backpack unsuspended, but only just now I discovered the reason.
please reproduce this bug and attach the /var/log/syslog right after you reproduced it.
