I am trying to load a backported drm module using dkms.
It is not signed so is listed as tainted and trace points are disabled.
As explained in the above article this is because the TAINT_FORCED MODULE flag is incorrectly set for unsigned modules.
The final patch to fix this and add a TAINT_UNSIGNED_MODULE that does not disable trace points can be found at http://lwn.net/Articles/588803/ (fixed in 3.15)
Please consider shipping this patch.
