What you did was instruct VOLK to use a non-SIMD implementation of these
two functions. It appears that for whatever reason the AVX versions of
those kernels are having problems when running on your specific CPU.
Can you give us the information from running:
$ grep 'model name' /proc/cpuinfo
What OS and version are you using?
Are you running in a virtualized environment like VMware or KVM?
