Message-ID: <202303281539.zzI4vpw1-lkp@intel.com> (raw)

Hi Marc,

First bad commit (maybe != root cause):

head:   a6faf7ea9fcb7267d06116d4188947f26e00e57e
commit: 3b16f6268e660f15aed0bb97aefe87e893eb8882 [6577/7309] ARM: mach-virt: Select PMUv3 driver by default
config: arm-randconfig-r024-20230326 (https://download.01.org/0day-ci/archive/20230328/202303281539.zzI4vpw1-lkp@intel.com/config)
compiler: clang version 17.0.0 (https://github.com/llvm/llvm-project 67409911353323ca5edf2049ef0df54132fa1ca7)

        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        # install arm cross compiling tool for clang build
