In some cases the printf() mechanism is too heavy and can't be used. For example, when debugging a race condition involving devres API. When CONFIG_DEBUG_DEVRES is enabled I can't reproduce an issue, and otherwise it's quite visible with a useful information being collected. Enable trace events for devres part of the driver core.
