Newer patches (Oct.-Dec.) did no= t work, even in RT_BASE mode. Varia hardware: One Opteron 285, 2-cpus (4 cores). Six Intel Atoms device= s kernels compiled as x86_32. I have my patches, but I tested both with them and without them. --- Behold! 3.12.8-rt11, RT_FULL mode, kernel cmdline: init=3D/bin/bash 1. bash: cannot set terminal process group (-1): Inappropriate ioctl for dev= ice bash: no job control in this shell 2. in single mode: After 2 minutes timeout: see screenshot http://i59.fastpic.ru/big/2014/0127/bc/0f9e04536181286f820ecaae5a8481bc.j= pg 3. command killall -15 freezed system!
