The failures that you only see with COMPILE_TEST=n are the ones that someone has previously decided can not be handled properly, for one reason or another, examples include: - rebuilding generated files that require additional tools to be installed on the host, e.g. CONFIG_PREVENT_FIRMWARE_BUILD - configurations that may or may not work but result in excessive compiler warnings that are not otherwise interesting, e.g. GCC_PLUGIN_CYC_COMPLEXITY - options that enable compile-time warnings about pointless configurations such as leaving out support for every machine - options that are unlikely to have an effect on testing but slow down the build time (e.g. CONFIG_DEBUG_INFO) for build bots finite hardware resources. On the primary architectures, randconfig builds with 'make -s' should generally result in no output from the build, and I would consider any output you get a bug. When COMPILE_TEST is disabled, there are countless known issues in configurations that make no practical sense. Arnd
