These two failures in the math tests appear to be harmless. The math tests may also fail on systems where the CPU is not a relatively new genuine Intel or authentic AMD. Certain optimization settings are also known to be a factor here. If you have mounted the CLFS partition with the noatime option, the atime test will fail. As mentioned in , do not use the noatime option while building CLFS. When running on older and slower hardware, some tests can fail because of test timeouts being exceeded.
