Or do you think > 3.14 brings some more details? I definitely fixed some FCSE issues in the ipipe-3.14 branch, mostly when FCSE is enabled without CONFIG_IPIPE. Now if ipipe-3.10.18 has no issues, whereas mixing Prempt-rt in makes some issues appear, I would suggest looking carefully at the changes introduced by the preempt-rt patch with regard to mm handling. -- Gilles.
