I've finnally detected the root cause of glibc-2.20 broken my system: 
glibc-2.20 start using TLX instruction which is disabled by microcode update.

disabling microcode update brings my system back to live!

so, there is either a bug in CPU , nor glibc has borken CPU feature detection.

It's likely you are hitting a kernel bug
