4.11 kernel results (with CentOS 7.4 glibc): https://gcc.gnu.org/ml/gcc-testresults/2017-07/msg00998.html 4.4 kernel results (with ubuntu 1604 glibc): https://gcc.gnu.org/ml/gcc-testresults/2017-07/msg01009.html Note the glibc does not matter here as I get a similar testsuite results as the CentOS 7.4 glibc using the Ubuntu 1604 glibc but with the 4.11 kernel. Also note I get a similar results with a plain 4.11 kernel compared to the above kernel.
