Hi Robin,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: c42d9eeef8e5ba9292eda36fd8e3c11f35ee065c
commit: f9bd34e3753ea8f1433a3ba70f03a165a1416f98 perf/arm_cspmu: Clean up ACPI dependency
date: 5 months ago
config: loongarch-randconfig-r133-20231107 (https://download.01.org/0day-ci/archive/20231115/202311151948.RANfH9T9-lkp@intel.com/config)
compiler: loongarch64-linux-gcc (GCC) 13.2.0
reproduce: (https://download.01.org/0day-ci/archive/20231115/202311151948.RANfH9T9-lkp@intel.com/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
