[hardy] Network manager causes CPU load to go to 100%

[Richard Seguin]

Binary package hint: network-manager

Network Manager 0.6.6-0ubuntu2 causes CPU load to go to 100% and will not connect to any wireless network. I am able to manually connect to a network using iwconfig. The problem started when I rebooted after a general system update for hardy.

This regression has been detected and corrected. Please upgrade your system.

[Steve Langasek (vorlon)]

Thank you for taking the time to report this bug and help to improve Ubuntu.

This problem was caused by a regression in the hal package, which was previously reported and has been fixed in hal 0.5.11~rc2-1ubuntu2 in the archive.

The network-manager package should eventually be updated to not rely on deprecated hal interfaces, but for hardy this issue is now resolved.

I have updated to hal 0.5.11~rc2-1ubuntu2 this morning (installed 8.04 beta yesterday as an upgrade from 7.10), and even after a reboot am still seeing network manager 0.6.6-0ubuntu2 consume 100% CPU. This occurs when I remove my ethernet cable and network manager attempts to connect to my wifi network. The following is from the syslog:

I can confirm that I am still experiencing this bug on an up-to-date hardy system, even after it was claimed that a fix was released.

[[e-mail] (kellyness)]

I am having a problem with Network Manager(CPU pegged looking for a wireless network) on an up-to-date Hardy system as well.

[Richard Seguin (sectech)]

It seems to be fixed as far as last nights update went on my side.

I can confirm it too on a fresh install of Hardy Beta, with all updates installed.

[Martin Gerdzhev (mgerdjev)]

I can confirm it too as of now with all updates installed. Here is the relevant section of /var/log/daemon.log
