Hi Eric, First bad commit (maybe != root cause): tree: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master head: 1c6f93977947dbba1fc4d250c4eb8a7d4cfdecf1 commit: 8d14224263d97d0d53061cf08c2fa911418b1b7f [12990/13166] riscv/kexec: refactor for kernel/Kconfig.kexec config: riscv-randconfig-r014-20230704 (https://download.01.org/0day-ci/archive/20230705/202307050034.tAJSN9qy-lkp@xxxxxxxxx/config) compiler: riscv64-linux-gcc (GCC) 12.3.0 reproduce: (https://download.01.org/0day-ci/archive/20230705/202307050034.tAJSN9qy-lkp@xxxxxxxxx/reproduce) If you fix the issue in a separate patch/commit (i.e. not just a new version of the same patch/commit), kindly add following tags | Reported-by: kernel test robot <lkp@xxxxxxxxx> | Closes: https://lore.kernel.org/oe-kbuild-all/202307050034.tAJSN9qy-lkp@xxxxxxxxx/ Note: the linux-next/master HEAD 1c6f93977947dbba1fc4d250c4eb8a7d4cfdecf1 builds fine. It may have been fixed somewhere.
