Thanks for your suggestion.

I tried the following change:

--- a/arch/arm/mach-imx/init.c
+++ b/arch/arm/mach-imx/init.c
@@ -78,7 +78,7 @@ void imx_set_wdog_powerdown(bool enable)
        writew(enable, &wdog1->wmcr);
        writew(enable, &wdog2->wmcr);

-       if (is_mx6sx() || is_mx6ul() || is_mx7())
+       if (is_mx6sx() || is_mx6ul() || is_mx6ull() || is_mx7())
                writew(enable, &wdog3->wmcr);
 #ifdef CONFIG_MX7D
        writew(enable, &wdog4->wmcr);


but still got the kernel reboot.

Any ideas?

Thanks
