This is yet another case of a hard freeze which started happening after upgrading to Ubuntu 12.04. The freeze usually happens when using Firefox to access something like a Youtube video. Though this is not always the case.
The upgrade was done about two weeks ago and when I did a update Friday the freeze started happening within minutes after the Desktop was powered up. IE: The problem was much worse after the upgrade!
The Dell is also freezing under Ubuntu 2d whenever I start Firefox!
The freeze is immediate and it has not happened under Ubuntu 2d with any other application.
