Comment 123 for bug 767192

@ethos_dacapo: Be sure you reboot after installing the kernel .deb files. After rebooting you can check what kernel you're using by opening a terminal and running 'cat /proc/version_signature'. If you're running the right kernel it should say something along the lines of 'Ubuntu 2.6.39-020639rc6.201105171845-generic 2.6.39-rc6'.
