I had similar issues - currently on kernel 3.4.0-030400-generic (got at http://kernel.ubuntu.com/~kernel-ppa/mainline/) and no freeze since then (a few days).
The only reason I did not use a higher kernel is because of the higher kernel numbers do not work with the current vmware player which I need for work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently.
