knowing the assertion triggered on wait_until_enabled() is not that useful without knowing what exactly caused the failure. It might be an user error, like too little stolen memory by the bios, or an actual issue in the kernel. So, let's make life easier, particularly for the CI, by printing the status before failing out.
