This bug was fixed with commit: 425933b30b0ccfac58065bca6c853ea627443cdf Greg has queued the patch for the next stable release (3.0.5). I wanted to mention this here because ARM boards may be suffering from stability problems due to mangled pad control values rather than PREEMPT_RT issues. John Ogness
