Hello Jaco, That message only appears if CONFIG_DEBUG_ATOMIC_SLEEP (sleep inside atomic) is enabled in the kernel config. The kernel configuration options I enable to test kernel code can be found below. Please note that some of these options slow down the kernel significantly, so these options should probably not be enabled on a production system.
