Hi, There is currently a bug in Linux 3.0 where the ARM pad control values will be set to 0 instead of being left as they were when NO_PAD_CTRL is used. 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.
