same for XT925 last KK update?A proper fix for the latest stock ROM updates can't be made until the latest kernel source is published by Motorola.
CM includes the fix for it for some time already, so if you want to get rid of it right now, switch to custom ROMs.
If you want to stay on stock ROM, you'll have to wait for the new stock kernel source release. As soon as it will become available, I'll upload the recompiled boot.img with the fix.
