Bug 767849

Description of problem:
Attempting shutdown, I am seeing an error message of the following form and the shutdown hangs:
[186454.6652103]NetworkManager[930]: <error> [1323907401.574780][NetworkManagerUtils.c:519] nm_utils_call_dispatcher(): could not get dispatcher proxy!


Version-Release number of selected component (if applicable):
During update to kernel 2.6.41.1-1.fc15.x86_64 and to kernel 2.6.41.4-1.fc15.x86_64. I don't know the version number of the relevant NetworkManager.


How reproducible:
Shutdown to reboot with new kernel. I don't recall this happening when I was not updating the kernel, but I rarely shutdown unless I am updating it.


Steps to Reproduce:
1.Run PackageKit to install updates including Kernel
2.'shutdown -r now'
3.

  
Actual results:
Shutdown hangs as above


Expected results:
System should restart with the new kernel and updated kmod-nvidia


Additional info:
Looks suspiciously similar to bug https://bugzilla.redhat.com/show_bug.cgi?id=676316 for i386 FC13, FC14.

After powering down and rebooting, a grep for nm_utils in /var/log/* turns up no hits, so I cannot find any logged information.

When the shutdown is being performed to boot to a new kernel, the hang seems to occur at a time before akmod-nvidia has had a chance to finish building the new nvidia kernel module. A file of the correct name exists, but is not a valid driver and this causes the display manager to not come up upon reboot. After reboot, therefore, I go to a console and execute 'yum reinstall kmod-nvidia{version}', in the hope that a kernel module for it has been released.
