Comment 2 for bug 183568

Calvin,
To the best of my knowledge there has been no progress on this bug. I had to update the linux image on my machine this morning; the update required a system restart. As usual, I had to do a manual power down to get out of the restart freeze.

Some of the related bug threads suggested that this is a pretty low level bug related to various hardware configurations. I'm not convinced of this interpretation because I was able to eliminate the bug by uninstalling network manager.

Are you using a wireless card for connectivity? If so, I might recommend that you use wicd as a workaround. I confirmed that replacing network-manager with wicd eliminates the problem. However, I've got a wired connection & wicd is optimized for wireless, so it wasn't a very good fit for me. I reverted to network-manager.
