press super key for enter the gnome shell Package: kernel Architecture: i686 OS Release: Fedora release 18 (Spherical Cow)
I had this problem before with self-built kernels, and it was fixed by roughly this range of commits: e041f65d5f00011049c7d6af0e31ce69ce9e2655..75be3e24eeedbc9ec5faf3483fe9b449abec94e8 I believe (or at least the rest of sforshee's tx-rework branch). It's now in 3.8.x; might be an idea to get it into Fedora kernels as it massively improves reliability as well as improving overall performance, plus would close out an abrt error.
