You mentioned this happens to all the kernels tested. Did this only start happening with the 3.0.0-22 version, or does it happen with other versions also? Are you referring to the various flavors for 3.0.0-22?

[C de-Avillez (hggdh2)]

This is actually a dup of bug 994247. I chatted with Tyler, and he tells me he does not consider this a regression anymore, just a bug that is going on.
